Thank you!!!! My system was blowing warm air intermittently at stops but mostly blowing cold again when driving, during a tire repair I had Firestone perform a $9.99 AC performance check, got the car back blowing warm air all constantly, manger tells me I brought in with a malfunctioning compressor clutch and it just died the day I brought it in convientiently the same day he quoted me $1200 for a new one!!! I asked what they did during their AC performance check and was told just checked the functioning of the compressor's clutch via an electrical test, this video is VERY INFORMATIVE for what they should have/could have done to make my car start blowing warm air. I'm a single mom and they're trying to take me to the bank, I'm going higher at Firestone or I'm getting a second opinion about a my AC system in my 2011 Kia Optima before I pay anyone a dime for a new compressor. I am madder than a wet hen!!!

Thank you so very much for passing this valuable info along to people like me who didn’t have a clue. And back in early 2000s the internet still wasn’t what it was then, like it is today.. vast knowledge just by pointing and clicking.

I watched 10 times over and I took my car to a repair shop. Thanks.

Took my car to AAA Auto Repair Center on Tully Rd in San Jose to repair the air conditioning. They told me that the compressor was bad (which I had already figured out since it had a frozen clutch..couldn't push it in by hand while engine was off). I know compressors cost about $300 but they were going to charge me over $1500 to replace it. Then, later, they called me and said they would have to also replace the receiver drier and that would cost another $400 or so. So, after I went back to pick up the car, I looked under the hood and saw a nice shiny new compressor but couldn't see the receiver drier until I got home. Turns out that the receiver drier is like welded to the side of the condenser and has a plug on the bottom that needs to be removed in order to insert a cloth-like cylindrical shaped tampon-looking "drier" that takes moisture out of the system. That's all they did...and they charged me over $1900. The drier "tampon" can be bought at auto stores for from $15 to $35. And the compressor can be bought for about $300. My car is a 2014 Hyundai Tucson. Once you take off the splash panel under the engine of the car and look up at the bottom of the "condenser", on the driver's side of the vehicle, you can see and access the "receiver drier" plug to remove an then to insert the "tampon". I couldn't drain the coolant into a collector before removing those parts so I had to have all this work done by "professionals". Funny, not, how the government will fine you big bucks if you let the coolant escape which helps contribute to global warming but they have no problem sabotaging gas pipelines like the Nordstream pipeline which belched tons of gas into the atmosphere for many days! It's no wonder we are having high, record, temperatures. Wars don't help either. Same thing happened after WWI and WWII..record high temperatures worldwide! Thanks a lot Putin...you son of a b...!!! Putin needs a "b" to the head!!!

Went to an aircon service and it took them 10 minutes to tell me my compressors is shot,I did have a blown fuse and replaced it before I took it there,never ever refilled the aircon since the car was bought but will go through the stages of advice you've shown me in the video. Thanks for the advice.

This video just proved I don't have a blower motor problem. As a matter of fact all I need is freon.I went thru step by step with another mechanic. Blower motor just blowing real loud and good.

First off, love the channel, and your easy to understand repairs and methods. THANK YOU AND KEEP THEM COMING. My 2002 Merc Benz S430 (W220) A/C stopped working after I replaced the windshield wiper hose (with the heater wire/ cable inside). The unit small red light is on indicating the system works, but will not blow cold air. The clutch does engage, on then off, constantly. The typical reset feature/ trick doesn't work for whatever this error is currently. I checked the relays/ switched and replaced them as well. Assuming the system may have been low on refrigerant, I filled it with what it took in, which appeared to be almost two full "tall" cans of AC Pro. Reset the system and the air came on "absolutely freezing cold" for about two minutes then shut off again. After resetting and attempting to make it stay on, it wouldn't reset anymore after four attempts. I noticed a clear liquid had leaked from the bottom center of the car down the driveway to the rear of the car, no smell or color, but thicker than water. The next day, with the engine running and the air refilled and reset once more, I heard a loud hissing and bursting flow of air or spray from under the hood, front drivers side for about 40 seconds then stopped. I believe it was a pressure relief vale of some sort !!! Scared the &%$#@^& %$#%^&%#@ out of me to be exact. The clutch still engages, on then off, constantly. Whats wrong with the cars AC ????? What would you recommend I check or replace???? No AC for the past four months now...

This totally worked for my 03 Camry.Thank You so much,I'm sure You saved me a bundle of cash.😊

What if all the time air is always hot no matter what and if driving high speeds, warm.air is felt through vebts

Still waiting for the info for the German auto type of compressor without the clutch.

When I start the car after 24 hours, the AC works fine. But when I drive half an hour and stop somewhere, turn off the engine and later, start it again, the AC won't blow any air inside the cabin. I hear something turning on however, if I push the AC button. But no airflow into the cabin. It won't turn on anymore unless the car is standing again for a long time (24 hours). Outside temperature here is always around 30 to 35 degree Celcius.

After having my radiator replaced the a/c was blowing hot air only What can be the reason for this change? Thanks guys. Toronto Ontario Canada💕

Very thorough explanations helped me solve my issues immensely.

I have a 2005 Saturn Vue and my AC only works when I’m driving or at a high rpm, when I stop the air gets warm any ideas as to what it could be, it was recharged and checked for leaks and none was detected

These types of videos help me senior citizen no one knows about cars.I am doing a/c because I changed battery and replaced after utube taught me

The blower fan quite blower there is a aluminum cooler that there are wire,s going to it that is inside of the vent down by the fan motor what is the name of it ?

this maybe one you haven't heard of yet. my wires were ate by mice to the point i can't locate where the wires goes. do you have a video showing the wires comes from and where they are connected and how many are they

you are defying the odds ... Next year in Florida you could display a classic plate !!!

I enjoyed the depth of explanation. You have a new subscriber.

Thank you very much for the channel...if the A/C is in a running condition, do I need to service or what should I do to keep the A/C in a good condition and keep it in a running condition. Could you please advise and give a few step or tips.

Hi have a i20 2016 aircon stop blowing cold i had a new compressor vale in but still did not work what can it be then my ac compressor or pressor switch

I've had a honda fit 09' for 2 years and the air was working fine then this summer it still blows cool but won't get cooler than 70degree, got acpro, check with just the gauge and it is in middle of green n everything is working, do it need alittle freon? Please help

How do I check the a.c. pressure switch connector when it has 3 wires black, white, and red?

My air conditioner doesn't work but my heater does.the speed switch only works on 4. I noticed the pully on the air-conditioner compressor or moter doesn't spin. One works but one doesnt.this is on a 2002 Mazda protégé. Please help me. I'm retired now and do all the work on my car myself. I'm so grateful for KZfaq

This is a great video. It’s not helpful to anyone that are not familiar with cars? Which is why people come to You Tube. To find simple answers and easy fixes. If not easy? At least understandable. But oh is very thorough.

I had mine looked at was told one of the hose has a leak...what do i do to fix that?

What would be the cause of an ac system cycling on and off at idle. Ac blows cold once the compressor and fan are running however stops blowing cold air once the cycle ends. Happens every few seconds during idle.

sir what is the reason expansion valve become bad and indication that expansion valve is bad

Make sure your relay sensor is engaged even if you have to bend the prongs😉

so I just bought a 2005 Chevy equinox, and have an issue I have not been able to find an answer to yet. On the lowest two fan settings the AC light turns on if I press it, but I can't hear the fan at all, which might simply because of how low the setting is. However, if I set my fan to high, or even the speed just below high the air conditioner button will not come on at all, but the fan definitely works at the proper speed. At no time does cold air blow out. I tried to add refrigerant to it, but it doesn't seem to have worked.

I have a bit of an odd situation and thought you might shed some light on it. My wife's 01 Kia Rio at this point cannot accept the 22 ounce full recharge despite replacing the expansion valve and filter drier. I can get about 6 oz or so of freon in and the gauges are reading 30 on the low side and 150 on the high and anything above this reading the compressor starts cycling. There is some cooling but it's minimal. Everything else seems fine. My thoughts are a clogged condenser or weak compressor. The compressor readings do seem to react accordingly to the level of freon. Any help would be appreciated.

For it was showing 86 psi whish is way to high I replaced cabin air filter and check the the compressor and checked if the fans were running

2008 Toyota Avalon. Had system checked and all good except after the alternator was replaced cold air only comes out the passenger and rear vents. Not warm but definitely not cold comes out the driver's side. We were told it was the blend door and the whole dashboard has to come off to replace it any help is greatly appreciated

Very nice video was very well presented and informative 👍🇬🇧 thanks

I have a 2001 Chevy Blazer with a fairly new a/c system, absolutely everything was replaced. Recently, the compressor stops altogether and does not cycle once the vehicle has been ran for about 30 minutes. The a/c works great when it works so I assume the high pressure switch it cutting the compressor off but not sure what the problem could be. Putting gauges on, the static pressure is about 100 psi, slightly higher than what was recommended in this video. When compressor is running, pressures are fine, according to a chart for my specific vehicle. Any help as to why the compressor shuts off when warm/hot would be greatly appreciated.

Good information, none of it applies to me but good info. I have a 94 Mercury Grand Marquis. It is working great when it is not too hot out or I don’t accelerate hard. It will quit working and not recover. It is common for the AC to work until I shut the car off then not work when I get back in five minutes later. 134 was a little low but still in the functional range. The high pressure connection was leaking. Fixed the fitting and brought pressures to proper level. About 40. Only next thought is to bypass the high pressure switch the next time it quits and see if it works. Any other thoughts?

hi there? I have an A4 2014 B8.5 1.8 model TSFI... I have a problem with my aircon. when you switch it on. It blows air, but the air only comes from the underneath vents by the feet and by the windshield vents (sufficient airflow by the way). But NO amount of air flow is coming from the side vents of the dashboard and the middle vents of the dashboard by the radio. what could be wrong? thank you for your suggestion.

Hi, I have a question. What exactly is it when my car does get cool but will not stay cool. It won't even reach the backseat. It fluctuates between cool and hot.

What could be the reason for an ac to blow warm air, when the system is filled properly, the clutch is engaging so the compressor is running and the blower fan is blowing like it should. ?? So happens on a 1989 ford e350 with a ford 460 engine. Thanks a lot..

Very Helpful Best Research I have found Explained Clearly 👌 😊

HI PROBLEM WITH 2009 3I 2.0 ENGINE my ac 10 amp fuse mark (mag) keeps blowing off and the compressor don't work but if I jump the fuse with wire a small wire it works again the compressor .what could be blowing the fuse .any help will be appreciated .

Mines is working just fine now… thanks❤️‍🔥

I replaced the A/C compressor with a new one do I need to add oil to it and if so how much and can I just recharge the system or do I have to do anything special before recharging

Good video but it does not give the complete Diagnostics my compressor works, my AC is full, my valve cover went bad but it was reading turn off AC due to high temperature all of a sudden it stopped blowing cold air, fix the valve cover now still does not blow cold air everything works in the car it's just doesn't blow cold air. Help

97 f-150 5.4 a/c clutch not disengaging. new switches put on high side and lo side, so whats next ? and which relay is it in box

I have an `97 ford ranger 2.3ltr.that has an A/C that when charged.Blows cold air.Then stops.Replaced.Compressor switch.Low side.Installed Dye to find any leak.Haven`t found. Any leak in system.Could it be the high pressure switch?

My AC stop blowing cold air after awhile of running in 80m/hr but it return after resting while no problem if im running below 60m/hr..... my motor and condenser is new. What might be my problem?

I have a problem with my 2009 Nissan Sentra The AC goes on but even on max inside the never get cold. The defrost works!!And I also noticed that when I look under the car On the asphalt I don’t see any water!! 😳😱. Thank you ..help I don’t want to get Robbed at the mechanic..

Thank you so much for your vid. Are you perhaps familiar with the issue where the aircon switches on and works for a minute or so and then just switches off ? If you switch it off and on again it will start up and cool nicely but then switch off again after a minute or 2. I have been searching online for hours and hours on end with no joy. Greetings from South Africa.

I have a 04 Accord and the air is blowing hot air. When I connected a gauge it read way in to the red zone. I used the AC pro they sell in the auto parts store.

On my 2000Ford Ranger a/c problem air is coming out the place where you put the freon on the low side how do I fix this without loosing my freon

system is full, a/c clutch engages, never diengages, but puts no load on the engine, like the typical bog from turning on the a/c and it blows hot air, dont know much about a/c systems, was hoping it could be fixed inexpensivly

Hi I’ve got a 01 volvo v70 my ac clutch works when I charge it but it doesn’t blow cold air but when I decrease the pressure in the ac my clutch doesn’t work but my air is cooler what’s could be the issue

Hi, how about if the compressor clutch stays engaged all the time? is there a problem with the ac system. air is cold though. thanks so much =) peace

so in formative... mannnnn thanks... Awesome Sauceeee....

A tech checked out my system and failed to make it work

My a/c will only blow on high. I cannot lower the fan output. If I turn it off while driving the defrost comes on. I can't turn defrost fsn off without turning car off. What part do I need to order?

i have a motorhome that is short cycling every 2 to 5 seconds with low side at 35 to 45 and the high side is the same with ambient temp at 77. would you start out with replacing compressor. thanks

My compressor kicks on and stays on, replace clutch cycling switch it kicked on and off couple times in driveway drove 20 miles and it started staying kicked on again??????

I have a faulty AC and dont need it and dont want to repair it. It is constantly running, I can't switch it of. Can I dissable it by removing the AC fuse?

Mine blows cool air but not cool enough. Help!

Hei.I have everything working fine, but when the car heats up to 90 degrees, the air conditioner turns off and does not work, and every time I turn it on it turns off, why? Greetings to you

When I go to push the button to turn on my ac the light goes out emediatley and the ac will not work any help would be appreciated

if i overcharged, would the compressor leak clear oil? would the system still hold pressure? because the pressure is holding

great vid man. i got a 2004 300m ac seem to work if the car is cool temp but as it warms up vents blow barely cold air. any ideas would be appreciated.

Am so thankful for this video. Watching from Jamaica.

Wow this nice! Having the same issue right now, and I have already checked a few things mentioned here with no issue but I still can’t charge the system, as soon as I connect a can gauge goes in red and will not drop no matter how long I charge. Still blowing hot. Compressor engage every time, electrical seem to be good. I just don’t want to be ripped off at a shop, any advice!

This video helped me immensely!!! Thank you!

How do I replace my cabin filter in a 2013 Buick LaCrosse

AC blows hot at idle or stopped while driving, AC blows cold once car is driving at normal road/highway speeds.. Tried to recharge system with AC Pro but the gauge on AC Pro would not read system coolant level, AC Pro malfunctioned twice trying this..

sir what will check carry out to declare compressor is bad thank you

With what tool do you vacuum down the system?

man. you dont say about the vw compresor. how it works and failiure. and about the valve on the back of the compresor. i have a problem on my seat. i turn on the ac but only the rpm increases. after i revit up it engage but is not as cold as it should. i replace my presure switch ans it does the same. what should i do? sorry for my bad grammer

If an A/C system is over charged, will the compressor kick on?

When attach the hose to the low pressure the gauge goes to high pressure (red area). Compressor doesn't engage and blows out warm air. Time for another compressor?

My AC is intermittent. It cools perfectly if I turn the unit off before I turn off my car, if I leave the AC running and turn off my car when I come back and start my car it will only blow hot air. To make it turn on I have to turn off the AC for 10-15 seconds, then turn it back on and the AC will begin to cool again. The pressure recharge kit gauge indicator was in the middle of the yellow, between the green and the red zones. Thanks for any help.

Good video!!! Nothing much been said about the evaporator. I have a ford expedition 2014 at 60k driven ,a.c. system is not cooling as it used to be have to keep the blower speed knob on 3 .and that was worrying for me. So took the car to diagnostics at ford service centre and he said the evaporator is all clogged . Need to change but cost is too high 1500usd. Any alternate solution . Thanx

2005 350z - High side (98 psi) (calls for w/ amb temp 152-194psi) idle -low side (45psi) (calls for w/ amb temp 29-42psi) idle -Pressures do not change with engine RPM -BLOWS hot air Compressor clutch works, in cabin blowing motor turns on, AC control switches work, all AC fuses and relays work. -No leaks are found using UV light -Compressor does not feel warm to the touch indicating mechanical binding of some sort. -condenser is clean and free of debre -System became hotter and hotter over the course of a week, till it finally blows only hot air. Any ideas? I am literally about to change it all.

Question: at first the ac light would blink 3 times and then over time it stopped blowing cold. Compressor is working, it’s full of freon, the actuators are not clicking so I don’t think it’s that either. The high pass tube is ice cold and sweating so for some reason it’s not blowing the cold air in the cab. Would the tube be clogged?

Good posting! I am trying to diagnose the problem on my 2011 E350 Mercedes. Sometimes the AC will not start at all, but if I shut off and turn on the car again, it works fine. Any idea what it can be? Thanks.

Your pressure sensor looks like the barewires are touching .lol

I paid 1500.00 to have evaporator core, heater core and compressor replaced but not blowing that cold like it should be? I'm definitely taking it back , but any other reason? 2008 Nissan Altima

A quick one. I replaced my compressor. It was blowing warm air in the left hand side vents. New compressor works fine except the vents that blow from underneath i.e to cool legs/feet. What could be the problem? They were working before replacement and only the compressor was replaced. Nothing else was touched. Thanks

Damn good video best ive seen for ac or parts

Well my compressor is turning but it's still blowing warm air. This is after I added freon and the gauge was reading a little low, but it was blowing cold air. A couple weeks later I decided to add more freon because after idling in the Florida sun it started blowing warm air. Once I started driving it cooled off but I figure it was just lower on freon than it should be. The 2nd charge seems to have fried the system because now it's continuously blowing warm air. The compressor is turning though.

I have a 2008 honda civic and none can seem to figure out whats wrong with the ac, the compressor cut on so does the blower fan and component but the second the compressor cuts on i lose all pressure on my l hose, please help could it be the pressure valve ?

My only car is a 1992 Oldsmobile Royale 88. My mechanic says my car is no spring chicken and never tries to diagnose my ac issues. I'm disabled and I get ssdi. My disability it permanent and I'm on a fixed income. So my mechanic usually gives me a good deal but if he wont try to fix or diagnose it..I dunno what to do

Very informative ty

Great Video. Thanks. I have a problem with my 2008 Volvo V50 A/C system. The charge seems to be fine but after awhile driving the system will turn off, It seems that if I turn the thermostat all the way down and the fan up high and drive at 70 mph on the freeway it will last longer. My thoughts are that the Low pressure switch is bad or there is moisture in the system clogging the expansion valve. I would like to hear what your thoughts are and a possible solution. Im in Florida and its starting to get hot.

How do you check the dryer to see if it's bad

good video, thanks for the guide

My car is blowing warm air but the Guage says I'm still full on freon when I turn it on a can hear a hissing sound coming from my vents is that a problem with the compressor?

THANKS ! A lot of good info. My Audi A4 2001 has no AC and blows hot, the fan in the enigine doesn't come on either. I ill ry the relay, pressure sensor then the fan clutch, thanks !!!

you guys are the best. saved me $300!!

very good video. very thorough, Thank you.

Thank you, saved me a ton of money.

I have a problem when I start my 2013 Jaguar XF it idles super high then drops down to normal it happens every so often, does anyone know what I can do to fix this or why it’s happening?

I have a 2006 Buick Rainier and the a/c still works but it has a really hot smell and a light haze of smoke coming from the compressor.Is that probably the clutch that needs replacing?

Do you have the A/C videos for GM cars and show how to recharge the A/C ?

Too complicated for me 😳 lol
