Honda Civic 2009 AC system blows warm FIX

[@marknease1631]

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

[@dannysdiygarage]

Thanks so much, I love making videos, especially when they help others, appreciate you

[@robertjackson7590]

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.

[@dannysdiygarage]

That is great information, I’ll share this in a future video, thanks so much for sharing this

[@shanewhite7864]

Just changed mine too! Works well now! I had no idea!

[@slicric7416]

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

[@dannysdiygarage]

Glad it helped

[@juanjz4081]

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

[@The_real_Overrunn]

How did you fix it exactly? Im having the exact same issue (coolish air blown at idle, alot cooler while moving) my blend door actuator moves when I change the vents from face, to feet, to defrost.. all of that. But it doesn't move at all when I change the temperature from cold to hot, and back and forth. But it does change the temperature.

[@ScottPowersArt]

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!

[@dannysdiygarage]

Awesome! Another success story, appreciate you sharing, these are the comments that keep me producing videos 👍🏼

[@LoreCraftForge]

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!

[@dannysdiygarage]

I appreciate your comment, glad I could help

[@Spanglish-KC]

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 ❤❤❤

[@dannysdiygarage]

Understood, I plan on going deeper into diagnostic on each code, videos like this take weeks to produce, there’s the research, scripting, then trying to explain in a way that the novice can understand and feel comfortable performing these tests, not to mention with tools that are available for the DIY home mechanic, shooting the video and editing my goal is to have next summer a complete AC diagnostic video, other than this AC video, many of my in-depth wiring diagnostic videos that I spent weeks on haven’t done very well, which tells me my viewers are wanting a quick fix, if not they’re taking it to the shop, the codes are in the description if you haven’t seen them, thanks for your feedback it’s very helpful

[@Spanglish-KC]

@@dannysdiygarage I think few people appreciate how much work goes into making these videos. I followed your process. HEADER TEST: 👎 result is light blinked 4 times. Now I have to figure out what that means AC RELAY: New relay did not engage 👎 🚫compressor (clutch) FAN TEST: ✅ VISUAL INSPECT: ✅ ACTUATOR BLENDER TEST: Don’t know where it is. So unless I can figure out what the 4 blinking lights on header test are I am guessing needs new compressor which probably means whole new system 😢😢😢😢

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.

[@badfish420]

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!

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.

[@dannysdiygarage]

sorry, I missed this comment, did you get this fixed and what was the cure?

[@chrisworld2]

@@dannysdiygarage not yet, maybe tomorrow actually. What ended up happening was the red 12 volt wire rotted off the electromagnet side of the clutch. It was barely connected, thus an intermittent weak connection and sometimes it would work sometimes not. I ordered a whole new clutch assy with pulley, clutch, electromagnet for $40. The replacement process is straightforward. Compressor doesn’t need to come off, Freon doesn’t need evac or recharge.

[@user-el6ip9zp2b]

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!

[@sarahwalters4428]

Yes, if you overfill the system it will cause more problems for you. If you're able to,Buy a gauge to test it. Better to be safe than sorry. Ac's are such a blessing and for me A complete necessity. I no longer have a thyroid soo it's no beuno not having AC right now. No one can pin point wtf is wrong with mine so I'm trying to do it myself lol. Ohh ohh get a gauge that shows you BOTH the high and low side! I hope you get it figured out❤

[@jasoncurry2515]

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?

[@ranger178]

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

I’ve also had that problem, years ago, thanks for sharing

[@Luger718A1]

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!

Awesome, great information, I appreciate you sharing this👍🏼

[@metzmatu8409]

There are 3 or 4 shims in there of different thickness. The air gap recommended is 0.35mm to 0.65mm (about .014" to .024"). Removed 1 or 2 that give a recommended air gap between the clutch plate and pulley.

[@jvlax780]

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.

[@RemmikRotus]

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?

The can has special instructions on this, follow the instructions on the can, but you are correct unless the can says different

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.

[@dannysdiygarage]

The ac is activated when the switch is turned on and condition are met, low Freon will cause the clutch not to activate also, check out this video also kzbin.info/www/bejne/n2qXc6lugMaJsKMsi=T2czxY_4fbN0ZBe9

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.

@@dannysdiygarage I have found out that my ac compressor comes on after 5 min of the car on, Then doesn't turn off despite turning off the ac and the fan on the climate control panel. I believe that is why my evaporator is freezing up.The relay for the ac clutch is fine. Would you happen to know what can cause the ac compressor clutch to stay engaged like that? Also the climate control panel shows no messages when doing the diagnostic check. I'm stumped

@@anthonyrojas9411 Most AC's have a thermistor/thermostat sensor/bulb attached to or near the downstream side of the evaporator. It's there to stop the evap from freezing up. Did you resolve the issue?

Quick question for you, your engine bay is so clean, do you powerwash it or just use a rag and some kind of detergent/water solution and wipe it down?

I’m from California, however once in a while a clean it lightly after a repair with low pressure

Is it true that we aren’t supposed to mix R134a and R134? I’m in Canada and my used Civic originally had R134a, and I heard that I’m supposed to flush it first.

[@dannysdiygarage]

True, not meant to be mixed
