Man! Where is your shop? If I ever need to send my car to a shop, I want to send it to you guys! You have to be one of the most honest shops out there. It really shows that you take customer satisfaction as a top priority!

did yall listen good. changed the pulley and the belt because wanted to eliminate that from the noise making. then used the scope on the compressor to make sure that was where the noise was coming from.... hmmmmmmmm people people people.... the scope should have been used first. now the customer had to pay for the tensioner and labor and the belt

I enjoy watching your videos. You are accurate and detailed. We just had an 02 Tahoe w/ dual air in the shop last week for a/c inop. Belt was broke. Knew pattern failure of slugging compressors wiping out and told them before we put one on. Had to see what the pressures were. Belt on with correct charge found tensioner noisy on first start up. Slight flutter on high side as well. A/c locking up then freeing. Found a TSB pertaining to this. Was very interested to see that the TSB also says to install filters in the system. System was about 41 deg.F, which is pretty good in a 90 deg. F shop. I personally think that inline filters just before and just after the compressor should be installed as OE, not as an aftermarket option. The sensors that are already in the car will give some kind of clues as to whether they are clogged. Some cars have reminders for other maintenance items besides oil changes, why not on a/c filters too?

Another great video guys. Good stuff. A little detail on the location of the orifice tube and expansion valve might be helpful. I know where to find them and what to look for, but only because I was showed by some one else.

Thanks! This is helpful for my Ford E-150 rear AC problem diagnosis too!

Thank you, this video show me where to find my rear expansion valve in my Chrysler Aspen 2007.

Great job excellent video i have an 01 chevy 1500 conversion van, rear air is hot, front is cold so i may have a plugged expansion valve!

Another great video.

Great help . Thanks for sharing .

Great info, thanks!

Excellent Video!!!

Very good information Sir!

by the way do u know were is the expansion valve on a 99 ford windstar?

I have a 2001 chev Tahoe under the hood the air conditioning tube are cold but it wont blow cold air in side. Do I need to change to orfice tube or is there something else wrong.

I have a 2003 chevy suburban last year the A/c worked great till right at the end of summer it all the sudden started blowing nothing but hot are I had the mechanic check it out and the Freon was empty the compressor was replace about 1yr. prior to this happening so I knew it wasn't that anyways he put new Freon in it and it worked great for about 2 days and then started blowing hot again there's no dye anywhere near the front lines and haven't seen any near the rear lines. is there a way to check it with out spending a arm and a leg buying Freon to put in it I need it fixed where we live in TEXAS and the heat here is sometimes over 100 degrees

Thanks for the tip.

This dude is a good mwchanic

Much appreciated good sir🙏👍

Thanks exactly what I needed very detailed. And my problem will be solved 😮

What is the valve solenoid by the seat vent called? The one that opens and closes the vent

I hope I can one day be as good of a mechanic as Dwayne

wow. it needs everything. complete rebuild and fludh. $$$$$$$. thanks Chevy.

I felt the pipes under the truck near the exhaust and only one is cold and other hot is that normal or do I have a plugged valve I have same symptoms of the vehicle you fixed on this video except the noise in the engine.

Muchas gracias por compartir su conocimiento y tiempo, además bien explicado su video. Además le comento esta información me ayudó para diagnosticar una Buick Enclave 2011. Reciba cordial saludo y abrazo fraterno desde el bello Puerto de Tampico Tamaulipas México. Es cuanto. A la Orden.

Great video - thanks! I'm trying to diagnose an issue with the rear A/C in my limo and the "touch" method has revealed that the expansion valve is likely plugged (both pipes are warm back there). I replaced the compressor but forgot about the orifice and expansion valves. Front cooling is mediocre, rear just plain sucks. I know what I need to do now....

Can’t thank you enough!!

Well done 👍

Nice review. How do you flush the system before putting it all back together? Compressed nitrogen gas?

Where is the rear extension valve located at ?

My Question is I have a 1998 Ford Club Wagon..and cold air is present at the vent but with the knob on high there is little air flow and it does have rear vents also but the same thing is happening with those vents so its consistent throughout

Hi you said something about it being cold but not getting air in the rear what exactly did you say it was?

Will this work on the ceiling vents? I get no air flow in ceiling vents.

Your video is very helpful.. Thanks for sharing.. I have a question I have a 2000 chevy suburban and for time to time the rear a/c will shut off it comes back on after a few minutes do you have any idea what I can be?? Thank you in advance

I have a 2004 mercury mountaineer and I had someone put refrigerant in my a/c compressor but the manual says it need 56 ounces and we only could fit 24 ounces. My question is is the a second a/c port in the rear of the truck.

and our hands to touch the pipes lol

how do you strght wire the moter blower resistor on a 2001 chevy tahoe

I have a question about a 2005ford explorer lift gate, and how do I take the liftgate of the vehicle and put another one on

dwayne is a good mechanic

That much debris in the system means it is all throughout...thus any new parts installed will soon plug up again and or be damaged...you need to mention the importance of flushing out the entire system before installing any new parts.

pls why mercury mountaineer accumulator is too hot when putting freon 03

My 01 Tahoe is doing the same thing. When I replace the compressor should I replace both evaporators and condenser along with flushing the system?

Glad the customer left satisfied after you touched his pipe with your hands

I need the ac sensor locations for a 2001 chevy suburban 2500 series. Thanks for the help!

I have an A/C problem on my Mitsubishi Endeavor myself. The A/C blows cold air sometimes and others the a/c light will blink. Pep Boys told me the error code u1111 and said I needed to take it to the dealership because it was a computer error. Is there a fix-it-yourself thing that I could do or I have to take it to Mitsubishi for this?

If you replace the rear ac expansion valve do u have to recharge the system

my 2004 trailblazer rear air stop blowing, checked fuses, was driving and it came on about 5 seconds and went back off a couple times, where do I start or how to fix

2002 tahoe had odor coming from only the rear cabin when ac is turned on. suggestions? also ac is blowing hot air in front and rear

i like your videos... explained real well. Can you do a video for fixing the air vents? I have air coming from the top and bottom. Just not the front vents (and rear but im watching this now...) 07 GMC envoy. 😃 Thank you!

thanks for the really good video. I have an 06 Dodge Grand Caravan and the back blower hasn't worked ever since I ran the battery down one time shortly after I bought the vehicle. I just never went in and got it fixed do you have any idea what that could be? I think it's just the blower. is it a fuse or something?

Nice.

so once you take care of the rear like that is there a place back there to add freon or is it all done through the compressor under the hood. Pls and thank you. It's a 97 suburban 1500 with a 5.7 front and rear air two-wheel drive

Do you know where to find the rear auxiliary control module?

Sir, I have a similiar 2001 Suburban with a freon leak. My detector can't find it in the front, so I suspect the rear. Problem: can't figure out how to remove the access panel. Help...?

i have a 2002 explorer the weather is getting hot and the problem is that i turn on the ac and in the front it give cold air but in the back its hot air. if anyone can help id gladly appreciate you

i have the same problem, were you able to fix it? what was it?

Do you need to refill something in the rear as well or does it piggyback off the same refill port in the engine compartment?

I have a 2005 Ford explorer, and I want to replace the entire life gate.What do I need to do?

He good thanks

I have an 01 express conversion van and i replaced the rear expansion valve for no rear a/c and it was plugged up so the guages read 200 on high side. And. 60 on the low side, pipes are cold and box where evap is, is also cold, rear fan runs but still no cold air?

Yes it was the a leak in the valve stem. Pep boys added stop leak and it stopped up the lines but I had that all fixed at a different place.

You have a 1999 Buick Park Ave. Ultra Dual AC drivers side blows hot air and passenger side blow cold air. How to diagnose the problem.

i have a 01 expedition and the ac worked great and last year a mechanic sucked out all old freon and put new freon in and both blew ice cold thru summer in las vegas then winter came stopd using now it blows warm air checked the guages and its full...i see the compressor kick on and off..

I have a 2010 Escalade rear ac not blowing any air from roof only tru the feet

Hello. Great video. How about if the rear blower does not turn on but the front AC blower works. Is it the fuse or AC blower actuator? Or something else? Thanks

Question my dad's 2004 gmc denali ac in the front blows cold air but the back blow hot air replacing these part will fix it?

I have a 2004 Chevrolet Tahoe LS 4.8, and my front heater doesn't work but my rear heater does... what do you think it could be??

Hi, my front ac. Is working ok but rear is blowing outside temp air. I do have a condenser leak on my front condenser so I'm low on freon and I have a new one on order. I'm wondering if it's possible for my rear ac to be blowing outside temp air and front ac to be working with low freon. Thanks for any help 2002 Tahoe

I never noticed because I never run the ac but one day I ran the ac and then when I turned off the ac, it still sounded like a fan was on in the back. Right where this guy was working. I turned off the ac in the front and in the back, made sure it was all off and there was like a fan noise still coming from the back. What’s that ? Anybody know ?

Where is this orifice tube located

Help.. Have a 04 suburban. No cabin filter. No flap door behind the radio. Replaced the blend door twice in case of a bad part. The compression is great/ the rear is ice cold, why is the front not cold? There has to be a flap some where else. I also turned the blend door by hand 90* when running feel the hot but cool on the other side. Help

I got cold air in the back but none coming out the front of my 2002 chevy suburban lt, could it be the blend door?

I have a 2003 yukon xl slt, the rear ac just stopped working. Can't turn on from front controls at all. Every now and then it will kick on out of nowhere, and won't turn off when I turn my truck off. I have power to the rear blower motor just not working at controls. How would I go about fixing this?

@Bobbyhax probably from the compressor.

could A/C compressor turn off the truck? I also got an 01 tahoe, with rear A/C but everytime I turn on the A/C. It turns off the truck and I need to mess with the fuel pump sensor to turn it on.

I'm wondering what caused all that gunk to build up. Burnout?

I have a 2007 chevy tahoe the rear air conditioner does that sometimes it throws hot air??? I need help

I have a 2001 Chevy suburban 5.3 rear ac how do I know if I have 2 oriface tubes or do I have 1 oriface and a rear expansion valve I can I tell please help

If you change the expansion valve and the pipes are still hot/warm....what would the next step be??

2005 Yukon Denali. I serviced the A/C. Had leaking Schraeder valve. Replaced that and orifice tube which looked brand new. Front blows cold. Rear is hot. I reached up under the right rear wheel well. The large a/c line was cold, the small one hot. Could this expansion valve be my problem? Thanks.

Yes, anytime you open up the A/C system you have to recover the refrigerant and recharge it when you put it back together.

@Bobbyhax Listen to explanation......compressor failure

Headed home

I replaced the rear blend door now the AC works but it only blows on low and medium high position does not work even after changing the resistor any ideas? 2011. E350

I have a 07 chevy tahoe that doesn't blow air from the back i was wondering if you can help me out to what can be some of the causes and if all tahoes have the back A/C located there where the older ones have it? please help and thank you in advance

Hi; thank-you for posting this video...I do have a quick question though, hopefully someone can answer. Is the rear system referred to as the auxiliary climate control system?
