I’m so glad that you have an 8th gen Civic since you’re a good teacher on diagnosis and repairs.

So happy i found this channel, my issue was the fuse I was sweating on my way home and now im ice cold again.

Great video Danny, a polite suggestion is checking the cabin air filter. I had my Acura's dirty enough to freeze the core and naturally stopped cooling. Swapped it and worked fine.

Thanks for the help Dan, just got a Civic '11 and they said the AC hadn't worked. Parts still spun, bought the relay plugged it in and it worked like a charm!

So my ac was blowing warm on idle but once I would go it would cool down followed this man’s first steps and turned out my cold to heater actuator was just stuck a little before all the way cold flipped it to hit the back to cold and fixed the ac issue lol what an easy fix

This saved me an arm and a leg. Had a bad fuse. Which obviously threw off the ac recharge reading. Replaced the fuse, recharged the ac and it works! It isn’t ice cold but it’s getting colder!

Sir, an excellent video. I am an automotive instructor and I think you made a perfect video.

Thanks U. This is one of the best videos I have seen on diagnosing problems. I am a novice so this was helpful. Couple of suggestions that might seem dumb to experienced follks. CONTROL HEAD TEST: More on codes. What they mean / look like. Point out turn key all the way without starting. ACTUATOR BLENDER TEST: Where located? Engine on or key just turned fully? FAN TESTING: Engine on or key turned all way only? What fans/location A/C RELAY TEST: Show compressor on/off. FREON TEST: Which port? I saw two. Thanks for this fantastic video. Your good teracher adn use a clear voice ❤❤❤

can't wait to sit in 48F lmao😁 just diagnosed it using your method and its definitely the expansion valve, although it wouldn't hurt to swap out all the fuses on mine

Great video, tha tip of pressing the buttons 1:03 down and turning the ignition helped alleviate some stress, no warning lights. Then I swapped the relays 6:39 as you suggested and it was a dead relay, so I bought a new one and AC is up and running. Thanks Danny.

Good sir one thing you didn't mention is sometimes it could be the in cab aii filter behind the glove box, if it's covered in dirt and leaves this will restrict the air flow as well. Awesome video in detail 👌!

Great video I had trouble with my 8th generation civic AC cooling properly. It was the actuator motor that controls the air temperature. Once it was replaced with a Honda oem part the problem was solved

Thanks so much for this informative video! I had watched other videos suggesting the A/C clutch relay might be the problem (it was), but I didn't have any way of testing the theory out without ordering the part first. I'm just not knowledgeable enough about cars to randomly try swapping things out and around without worrying I'm going to cause some sort of catastrophic failure, so I rely on people like you to give me the confidence to try this stuff out without worrying that I'm doing something wrong. It was your suggestion to swap the rad fan relay with the A/C relay that helped me pin it down as the definite cause for my A/C issue. So thanks again, I appreciate the work you do!

Absolutely magnificent. I found one of fans disconnected but that didnt solve it. Only cold air only coming from one side

You are the best . Help me fix my AC it was my relay. I would have never guess

Thank you Dan. You fixed my a/c just by doing the 1st step because it’s hot here very hot

just fixed the AC on my 08 Civic with an $11 relay - thank you so much!

This video is one of the most solid automotive how to's!

The AC relay trick worked for me! Thank you!!

Thanks for the video. Towards the end of the video I was thinking "no wonder why mechanics get paid so much! That seems like a a lot of work. My 2016 Civic just started blowing warm air. I may take it to the shop and see how much they quote me to get it fixed.

I once hit the ac compressor with a hammer gave it a nice good hit and worked a charmed

thanks! I think i'm still gonna go to the rip off garage but at least I understand this stuff better thanks to you. my a/c will get super cold but unfortunately it takes about 1/2 an hour for it to happen and most of my driving is 20 min or even less - doesnt' ssound like long but like you said 90's gets hot quick

my actuator had snapped in half, thank you for this video, you saved me 😂

Very instructive, as always. Thank you!

So a guy was trying to help me and connected the freon can but nothing would go in It seems to me that Honda has the worst air conditioning system ever built. Myself and both of my sons have Honda vehicles with dead air conditioners. It never happened in my Toyota's before

THANK YOU, Mr. Danny n God bless 🙌

Amazing video. All clear. My Honda 07 Lx It makes a short circuit when removing and installing the air conditioning fuse, and it seems that the fans are going to turn on and it turns off, the compressor also does not turn on, I already checked the relays and if they work, also the internal control unit.

All video is prefect stap by stap is working good ..normally how check the working AC ..this is very important in your knowledge. . Recently I was worked my honda civic automatic (Ac work...) mhachanic told me your ac is not working(I am living in uae ) I asked why?? He told me ac unit is not working and GAS problem. You go and perches the new Ac with vlues and relye. .but I inses (total parts experience 1100 to 1200 Aed) w/o labour charges..I told any opinions? He is intelligent (from pakistan ) Yes I have solution. .he told me I try my best ..and he cleaning the Ac by presher and fill compresor oil in Ac and new Gas filling and fillter change. .my Ac is good working and best performance and setting half and helf 3 to 4 points only and chill cooling. .and I save my money and time. Total amount with labour only 200 aed....I AM very happy and Ac working good (that is true)))) recently 6/7/24... (that is posible? ???? Plz reply

My 2013 civic just started instantly blowing warm on my way home, went cold for 30 seconds again and back to warm. Owned it for 10 years 110,000 miles and this is the first issue I’ve really had with the car lol. It’s also extremely hot outside right now and one of my suspicions is the system kicks off when it’s too hot.

Great video another easy test the metal hoses neae the valves should be ice cold when its on

Danny when I use the a/c the vent closest to the passenger window blows cold but every other blows hot air. I changed the vent actuator

you help me today, my relay was bad and i almost buy a new compressor 😂😂

I had problem with 2007 civic where clutch only engaged sometimes the hotter it got outside the less likely it was to work so we took ac clutch plate off through wheel well it is a common problem and took out one spacer shim washer and cleaned rust from back of clutch plate with wire wheel the few thousands of the shim had it working perfectly after we put it back together and it has worked for years since then

Thank you sir…your video was excellent and great tips to troubleshoot ac problems.

DUUUUDE IS A LIFE SAVER!!! Thanks!!!

Very helpful tips. Thanks a lot my dear friend. God Bless you!!!🙏

I have the same car. Ac clutch engages and freon is in the sytem but no cold air. The blend doors work fine.

My 2011 CRV ended up having clutch engagement issues due to wear and tear increasing the spacing between it and the compressor. Removed it and removed a spacing shim to reduce the gap back within spec and now it engages and blows cold!

Thanks for making the video! Was hoping it would be the easy relay fix, but I'm now thinking it's the clutch because I've seen others mention the thing about heat causing it to stop.

So I have a little bit of an odd issue. When I bought the car the ac would not blow as cold at an idle but would blow very cold while driving. Now it consistently blows much warmer regardless driving or not. The clutch on the compressor engages. Both fans kick on. And the dummy gauge reads that it has refrigerant in the system. I’m thinking either blend door actuator or possible the expansion valve. I already pulled the cabin filter and cleaned it out.

Danny help me out. My AC works and the clutch engages and disengages like its supposed to for 10 minutes then it just quits and dont engage again. Does this sound like low freon? I tried recharging it with freon a while back and i tried the fuse swap nothing. Everything else looks fine like u mentioned but i don't know what to do. Should i try to recharge my ac again maybe i didn't do it right??

I think this video needs to add changing out the fuse and relay. That fixed my problem because I saw that the clutch was not engaging when I turned on the A/C. There's no problem with the fan or the system holding pressure.

What if the ac system which is the button doesn’t work where it should be so what could be the issue the button malfunction

My pressure system is messed up and the low side has high pressure and the high side has low pressure. What do I do? Jot trying to go to mechanic

well done sir! professional and logical!

Hi Danny thank you. You are a teacher. I changed the relay because the AC was intermittent in my civic 2008 then the odometer cannot be modified and also the AC continue intermittent. Advice please

Best video so far

When adding Freon you should purge air from hose or else your adding air to closed system. Which can result in ac not working properly.

Trying to figure out why the ac blows cool on passenger side vents coldest on far right and hot on driver side vents

My issue is the worst one…compressor clutch will not engage even with giving it the love tap that Danny did. A/c relay sway with radiator swap also did not engage the clutch…

0:32 man just called us all out lmao 😂

Worked for me..thanks alot...just had to reset

This video is excellent

Very detailed video. I'm happy that I looked at your video!👍

You are a GREAT teacher ! 👍

Amazing video AC working perfect now thank you.

Hi great channel helped me alot can you do a video for 2006 Honda civic LX oil consumption and pcv valve replacement thank you sir

My radiator fans stopped working when turning on the ac. It does work for the coolant.

I replaced my clutch and magnet I had the ac running properly for 3 days then started blowing hot air. Freeon was topped up and relay was changed. I. Wondering if it's the expansion valve?

So what if my recirculate light is flashing?

Danny - I didn't get any codes from the control panel at 2:09 in the video. At 2:26 in this video, the 2nd mode/button from the left on the control panel is NOT working properly. This is the button where there is an arrow pointing to the face and an arrow pointing down to the floor. The light comes on OK, but the air is ONLY coming on at the bottom toward the floor, NOT at the top toward the face. I did notice that if I select the 1st button, with the arrow to the face, and the 3rd button with arrow pointing to the floor separately they both work. What could be the issue?

Thank you sir you're amazing for this video

Correct me if I’m wrong but when filling the low pressure side are you not supposed to keep the can upright and 45 degrees max to keep liquid from going into the low side? Can’t compress liquid, right?

Thank you for the video I have CRV 2007 the AC is not cooling enough I add some frion but still the same could you please help me thank you

I checked relay switch. I get hot air compressor dies not come on at all

Thank you so much Sir you hust solved my issue

Thank you so much mine was the relay i switch it with another and the ac starter working .. thank you thank you

Well you're over 10,000 subs. So mechanic filled with new freon and the A/C got cold, but a few days later it was blowing warm air. Mechanic did not detect leak. Clutch kicks on. Your thoughts?

I’m also having an issue with my Honda civic not having ac. A few of my buttons don’t seem to function especially the defrost and no cold air? Anyone have any tips or guesses?

Great video but no explanation of what's wrong if a test fails. For example, my mode is stuck on defogger.

so the actuator moves when i change where the air flow goes, but doesnt move when i turn the nob from hot to cold. do i replace it?

yeah you are the truth!! good video i will be trying this

Thank you so much my heat wasn’t working and this video helped a lot

This video was helpful! Thank you

So the only fan, the drivers side, turns on for me. Gotta figure out why and if that's my problem or if there's more to it.

not sure if you experience this situation I am currently having on my civic aircon.After driving a while longer with AC on turned at the lowest temperature, the ac starts blowing hot air, it literally just heats up instead of just not blowing cold air. with AC on putting it to low temperature cant defog, now I can only use high temperature to defog. It does has compressor clutch engaging all but blow wrong temperature. what component do you think it could go wrong? The ac blows normal cold air varies from different temperature I set, most of the time while the car has been driven like the first 15-20mins after a certain time, that symptom starts.

What made you come to the conclusion that it was the expansion valve that needed replaced?

HOLY FUCKIN' FUCK!!! YOUR "NOT RECOMMENDED" METHOD WORKED FOR MY CAR!😂😢 THANK you so much!

Danny, is there any danger in adding Freon if Freon is not the issue? I suspect that is the issue with mine, but I do not have a thermo to test the before and after. Is there any danger in adding some Freon and then checking if the AC blows cold after? Thanks!

What does it mean when the circulation light keeps blinking? After doing 1:25 please help.

Thank You for Video ! Very helpful

Thank you so much you video help me to fix my Ac issue. God bless you :)

Hey so I have a 2010 Lx, mine blows very cold for about 10 minutes then becomes hot, I ran the diagnostic and it blinked 4 times as I’ve also been having trouble with the buttons, could that be the reason my ac is blowing warm also or do I have other issues?

great.

My clutch is engaging, but AC not cooling like before. Can it be a relay issue or need more r134?

What a friend, I did the test and it blinked 9 times, what it does to me is that I turn on the air conditioning and it turns on the compressor and fan and it turns off after 10 seconds I hope you can help me

Thanks Danny. You da man!

Hello Sir, When i turn on the switch the two buttons has to be pushed before turning on.. and after i turn the key on the first light goes off and AC light never turned on (what’s the problem here) ??? Please suggest

What do the blinking light holding the recycling button on my condenser fan is not getting any power maybe that's the reason

Exelent video Here's is my issue 2007 civic we replace the ac compresor,expansion valve ,new condensor car still Not blowing consistenly cold air note the compresor clucth engage only for 7 to 10 seconds then turn off any advice what also we have to do please help apreciated

This is great man, good work

I noticed in my civic the compressor 9:37 or clutch isn’t turning on.

Very high quality made video, thank you so much! I’m curious: I believe our ‘09 Civic needs a new compressor clutch. If i’m not mistaken, the compressor clutch SHOULD be spinning once A/C is activated, correct? Ours is not activated with A/C on and is blowing very warm air. It will only work for around 10 minutes at the start of everyday - consistently. Curious to hear yours or anyone’s thoughts.

Hi Danny, thanks for the informative videos. I did the test on the head unit on my 2009 Honda Civic and the light was flashing 4 quick flashes repeatedly. What does that indicate? My ac doesn’t seem as cold as it should be. Thanks John

I just had a new air conditioner put in in my 2010 Honda civic in January, now that it’s starting to warm up I decided to turn the air conditioner on it’s almost the beginning of May and nothing. I don’t think they’ll charge me for anything, if it’s not working, it’s on them I hope.🤠

The fans are not turning on. What might be the issue??

May i ask y a question with a ac issue. I have a honda 2008 mk8 1.8. I filled the ac up with coulant. I replacement the relay I can hear the ac pomp working. I checked the same wire. I have 1 connection instead of 3, it works. The H intake feels cold but the L intake feels warm. Still the air isnt cool inside the car. What could be the problemen?

My radiator fan works but condenser fan won’t turn on, and my compressor turns on when I hit it with a screw driver, does that mean I should adjust the shim?

Thank you for your help!

What about blowing cold while.moving but when sitting still not as cold . The system works how to check for that problem
