Car Owners Face AC Malfunctions

“I don't have power at the compressor. Should I have continuity between the a/c relay and the plug at the a/c compressor? If I don't, does that mean there's a break in the wire? And where the wire changes from pink/yellow to red/yellow, can someone point me in the right direction to find that joint? submitted by /u/Werrion123 [link] [comments]”

“Hello so I drive a 2002 Honda Oddesy. I had to get jumped today because my battery died once it started up my front ac and heat stopped working and the back is totally fine. It makes a click when you try to turn it on. I had this happen one time a few months back but it fixed itself shortly after. Now it hasn’t been working at all and making it hard to drive. I have no clue what’s going on so any advice is extremely needed !! submitted by /u/Ok-Introduction-8612 [link] [comment”

“my ac compressor was squeaking like crazy and then failed and caused my engine to not turn over. 3 weeks prior to this the ac in the car completely shut off when driving on the highway no blowing air not even the ac digital display being responsive or turning on. i ended up having the compressor taken out so i could get on the road. they qouted Me somewhere around 380 to bypass it and about 800 to have a new compressor put in So that I could still have ac. i went with bypass because i didnt have”

“Hello, question . Has anyone dealt with my problem before if so how did you fix it ? Well I’ve got a 2007 Honda Crv with about 160k miles , I bought in January of this year. I’ve put about 20k on it since then going on trips. About a month ago I started getting the problem: my ac blows super good and cold when driving going high speeds but when I come to a stop sign or red light it does not blow cold air anymore . It stops completely and instead blows like a very light warm air . No lights have”

“I have an '05 Civic 270k mi and have AC leak. Right now, i don't know where the leaks are and AC doesn't turn on due to low refrigerant. This has happened twice in past 5 mths and adding R-134 brings system back to life and goes strong for 2 months until it leaks out and then compressor doesn't come on. So, what is best way to find the leaks beginning at this point? I have a blacklight so should i add can of refrigerant with dye and look for leaks? I already know I'm going to”

“have a 2016 Honda civic with less than 30 k miles. I’ve been having issues with my A/c and have taken it to the Honda dealership where they changed my evaporator and the compressor seal which was cover under extended warrant. the evaporator had to be changed twice since the part was faulty both times and was leaking within about 1/2 months. since they changed the evaporator the very first time my car began hissing and making a gurgling sound on and off. I’ve taken back about 6/7 times and they s”

“Hey everyone, could use some advice on my 2015 Subaru Outback A/C. ​Around Christmas last year, the blower motor started acting up—it wouldn't turn on sometimes, but since it was winter, I just let it slide. Fast forward to summer, and it started happening constantly. I did some YouTube troubleshooting and found the classic "give it a whack" trick. Sure enough, hitting it made the A/C kick right back on and run great... until about a month ago, when it gave up completely. Now it on”

“It just blows hot air. Ok sometimes it'll blow a little bit of cold but that's rare. Tried refilling the freeon that did nothing. The vehicle has been in a front end collision that resulted in the radiator needing to be replaced. Condenser was never replaced though. Most likely suspect? submitted by /u/NefariousnessNo4215 [link] [comments]”

“I drive 2009 honda civic ex. I bought it august 2025. Ac was running well. Due to snow, use of AC was minimal. For summer this year, ac is just blowing warm air. I tried ac recharging but the hose detected that low pressure port is above 60psi. Outside weather was pretty hot that day though, not sure if that might be the cause. So i did not recharge with refrigerant. Any suggestions? submitted by /u/cristk [link] [comments]”

“Hi, I have a 2005 Acura TL with a condenser fan problem. On a cold start and turning on the A/C, both the condenser fan (driver side) and radiator fan will spin. When the car is at operating temp, only the radiator fan spins but not the condenser fan, and the A/C blows a little less colder when idling. My car’s coolant temp started ticking up past halfway towards H w/ the A/C on during a hot day in city driving, and turning off the A/C causes the coolant temp to return back to normal. I’m not su”

This is the second time Ive replaced the first 2, the first time being summer 2023, as there's a known issue and extended warranty with them. This time they said, and sent a video, of the evaporator leaking so I replaced it as well. After around a week or two, I noticed that the AC would stop blowing cold intermit”

“I have a 2013 3.6 ram 1500 and recently my ac stopped blowing completely. I took it to a mechanic and they told me the AC control head isn't getting power and it would cost me $2000 to fix. However when I turn the AC on I can hear something kick on like the blower motor but I'm not sure if it is or not. If the AC control isn't getting power should I still be able to hear something kick on and if so what should I do next? I did order the AC control head from a used parts place that co”

“Original issue: AC blows air through the windshield defrost vents, but nothing/barely anything through the passenger-facing vents. Pattern I’ve noticed: ∙ AC works weakly in the morning/evening (cooler temps), but stops working around midday/3pm when it’s hottest ∙ Blew full blast for ~5 min one morning, then died. Turned the car off/on after parking, it worked again for a bit, then died again — so it works, cuts out, and restarting the car brings it back temporarily. ∙ Noticed the compressor cl”

“hello! so basically the AC works sometimes and doesn’t other times. it just seems random when i turn on the car if it works or not. when it doesn’t work there isn’t any air blowing out at all, but the ac light still turns on and when i put my hand up to the vent and it feels slightly cool, so it seems to still be cooling but just not blowing the air out? any ideas on this? could i fix myself or worth just bringing to the auto shop? submitted by /u/FalseWeekend4 [link] [comments”

“2015 Xterra The AC on my truck stopped working from one day to the next. It blows air, but not cold. The heater works. It did not gradually go out. I took it to a mechanic to diagnose. He charged me $75 and said it needed oil. The next day it’s not working again. It blows air just not cold. When he added the oil it blew cold for that day. Did he scam me for $75? Is this a normal diagnostic that a mechanic would do because I would think that if you don’t have to add oil normally that’s not a fix.”

“Hi, I have a Škoda Octavia II 2005 with the Climatronic auto AC unit. I had the coolant refilled a few months ago, they said there was barely any left. The cooling didn't work at all before that, it has been working since, but I feel like it's not strong enough. I have to have the vent pointed at my face in order to feel somewhat comfortable. I still sweat a lot when driving and once I turn off the engine, I feel uncomfortable again within 2 seconds. It also takes like 3-4 minutes to sta”

“I hope this is the correct subreddit for this, but my car has been having ac issues for two years now and keeps going out. I first brought in my hyundai elantra limited 2013 ( 1.8-liter 4-cylinder Nu engine) to the mechanic because the ac was blowing hot air. They filled it up with some coolant and called it a day, i was happy and my ac was crisp and cold. A few months later and it’s blowing hot air again, take it back to and they replaced the hoses, the compressor, and refilled it back up. Work”

“Honda CR-V 2018, 106k miles Hi mechanics! I was hoping for some of your two cents, as I largely distrust the information Google AI (lol) wants to give me. I have been having an issue with my AC for the last 2-3 months wherein I will be driving with the AC on high and it will blow cold, continuous air on high as it should be. Sporadically, the air pressure will decrease significantly and suddenly by half for a bit, then will suddenly jump back to blowing air on high. The air never turns warm or s”

“We have a 2018 Fiat 500, the AC stopped working early last summer. We had it looked at, they supposedly refilled the gas and it leaked out, they tried to find the leak but couldn’t. We then had another garage look at it and they were suspicious as to whether or not the first garage actually re-gassed it in the first place. There were no signs of gas being refilled and they also couldn’t find any leaks using the purple UV stuff they use to detect a leak. We also noticed quite a severe scratch on”

“Hello, I was driving my car when I realized the AC was not blowing any cold air; I turning it to the hot side made it hotter but turning it to the cold side, even on max AC, made it only less-hot. I checked to see if the relay was the issue by opening my fuse box, taking out the horn relay and AC relay, and putting the relay from the horn slot into the AC slot (thus leaving the horn empty). I turned the car on and nothing changed. I suspect I ran out of refrigerant or something. So, I then took”

“I have a 2009 cobalt LS that I’m trying to fix for my daughter. The air conditioning unit was emitting hot air, and I discovered that the compressor wasn’t functioning properly. Therefore, I replaced it. However, currently, the air conditioning unit doesn’t produce either hot or cold air; it operates normally. I’ve installed the A/C Pro R-134a Refrigerant Kit with Stop Leak and Charging Hose, which is 18 ounces in size. Despite this, the air conditioning unit still doesn’t produce cold air. Any”

“So 3 days ago my ac 'stopped working' well the compressor went to 12 bar (the AC is at 1000g charge) and the temperature of the vapor went from 30 to 20°C but after hitting 20°C it started rising to 30°C, the same as the left and right radiators. The compressor clutch is a bit rusty but engages properly, it just has a bit of noise. It has the error eb1416 auxiliary water pump short circuit. If I erase the errors the ac starts working again, but does the same cycle, goes to 12 bar (14bar”

“I'm working on trouble shooting my AC system for my toyota camry 2012 LE. It stopped performing like it should about a year ago. The right 2 air vents blow slightly cold air and the 2 left vents blow hot air. The low pressure line does not feel cold when the AC is running. The fan for the front of the AC unit does kick on. And it sounds like the compressor is kicking on and off. And I checked the heat/ac vent actuator to see if that was working and it seems to be operating as intended. Pleas”

“At idle I have a heavy vibration when the A/C compressor kicks on. I was thinking that the compressor is going out. Could it be any other issue besides a failing compressor? Has always had a slight vibration when the compressor kicks on but has gotten worse since I’ve been using the A/C more often. A/C does get plenty cold while driving and gets a bit warmer when idle which is normal. Any advice before I spend the money to get a new compressor and spend my time installing it. I used to work at a”

“Have a 2010 civic lx and its just blowing hot air at this point, as the passenger fan is not working unless i take my hand and spin it (and sometimes it moves fast, sometimes slow).

“I'm not super car savvy the most I've done is change the liquids in my car in intervals (oil every 5000 transmission fluid every 100,000 coolant 30,000 etc) So after checking if my compressor is spinning shown in video, the refrigerant pipe (idk what it's called) is getting cold and checking my air filters idk why my AC is so weak (not the air flow just how cold it gets) It still barely gets cold and the car hisses when I turn it off not sure if it's compressor or something else”

“I have a 2010 rav4. Absolutely love this car, but the AC has been acting weird. It’s blowing out cold air still, and hot air if I want it to. So temp is fine. It’s the airflow that’s messing up. It gradually went out, and eventually stopped entirely running when I’m at a complete stop. It will run a bit when I drive, depending on my speed. Highway is normally fine but still a pretty weak blow compared to what it should be, on streets it will blow slightly but not as much. It does however send ai”

“My girlfriend's Honda recently started having a couple issues related to AC which I thought were separate but may be related. I'm mechanically inclined, but certainly no mechanic. First, she started getting a musty odor in the car, which overpowered her air fresheners. She once had a weatherstrip leak on one door (only in a carwash) which never returned. So I was pretty sure it was the ventilation system. I used a duct cleaner sprayed in the cabin air intake, checked the cabin air filter”

“2005 Nissan Altima 3.5l. AC working fine for years. Alternator goes bad so I replace it. Next day the AC doesn't work. Meaning it juts blows ambient air. For several days it doesn't work.

“I have a Pontiac Vibe 2003 My car's air conditioning died recently and I bought the A/C Pro product, but was checking it out before I cut all the stuff/straps in case I need to return it. They have you hook it up to the AC port on your motor and see what the gauge shows - I tried that with the car running and all, but the gauge showed red which is supposed to be overfilled, but my AC doesn't blow cold at all and there's no way it's overfilled.

“I have an 03 Accord sedan 2.0L and the AC blows hot air. The ac compressor doesn't power on, I checked that the pressure was alright (low side 85 psi) and the pressure sensor has 12V on one pin and continuity across it, so that checks out.

Then I measured the pins that the relay connects to and realized the computer is not grounding out the control pin!! (The load an”
