Civic - Honda :: 2008 - At Coolest Settings Vents Are Blowing Warm Air
Oct 17, 2015
History: A few months back I had a leak repaired in my cooling system. I noticed the other night that my radiator was nearly empty again, so I've filled it back up, but haven't fixed it yet.
As summer is over, I no longer need my AC. However that caused me to notice that at its coolest setting, the vents are blowing warm air (maybe 15ยบ warmer than outside) and that seems high to me.
My immediate thought is that the heater control valve may be leaking/damaged/corroded.

I have a Honda civic 2011. Sometimes my middle two ac vents is not blowing out any air at all ( but the sides somehow works very little ). The reason why I said sometimes is because it stopped working for a day then it would work again the following day. I don't know what's wrong with it. I called for an estimate and the guy tells me if he has to open up the dashboard to open up the vents it would cost in upwards of 800.

If the outside temp is cool (say below 75) the a/c works, but as soon as the day gets warm it starts blowing only warm air. I took it to the Honda dealership and they said that it was low on freon and that it needs a new clutch and a new coil. They recharged it and added dye. A week later I took it to a good independent shop that specializes in Honda repairs. They said that the compressor has power and ground and is full of freon and dye but they found a bad thermal switch and that I need a new compressor. I have no understanding of car a/c systems and thus don't know which repair sounds like the right one (if either) based on the diagnostics that have been done.

The A/C on my 2004 Accord has started blowing warm air out of the 2 driver side vents, but still blows cold air out of the 2 passenger side vents. It also occasionally blows condensation out of the 2 cold passenger vents. When this same thing happened last summer, the condenser and compressor were replaced within 3 weeks of each other. It is less than a year later and the same problem is occurring. Even more odd; every once in a while the 2 driver side vents will blow cold for just a few minutes, then revert to blowing warm air. The car does not have dual climate controls.

Is it true that on auto setting there is no air blowing out of the center vents? It happened to me this morning with my 2016 GTI.

I've recently purchased a 2007 Prius and I just noticed few days go that A/C blows warm air (weather was fair when I bought it and I can't remember if it really worked or not then) and middle vents do not blow any air. I'm not sure if two problems are connected but I do want to get both fixed without spending $$$ at the dealership. Where can I start?

The other day in 90 degree weather I found that the left side vents where blowing warm air the right side is blowing cold air ,I checked the settings and vent controls to rule out driver error. Living in South Florida A/C is not an option its a necessity. Especially driver side air.

I have a 05 Avalon XLS and I've just discovered an issue with my climate control. It's that time of year that things are warming up so we started using A/C and found that driver's side vents are blowing warm air while passenger side vents are blowing cold. I've tried varied temps and dual mode on and off as well as auto and manual control. Nothing makes a difference. I suspect some sort of thermostat for the driver's side, but I really have no clue.

When I start my 1999 Honda Civic, a sort of sulphury smell comes through the vents. I ended up having my compressor replaced today, and I assumed the smell would be clean, because the a/c is new. (Tells you I don't know much.) Anyway, the smell is still there, along with a smell from the oil (I have a small oil leak) and engine. It all goes away after a minute or two, but is this anything to worry about?

We have a 91 civic whose air conditioner doesn't work. The coolant level is good, and the compressor is running, but we only get external air coming through the vent.

2003 Civic, ~180,000 miles. Previously had overheat problems, replaced head gasket, timing belt, water pump, thermostat and hoses (+ a few other things) No longer over heating, but there is no heat coming from the vents unless the car is over 2,000 rpm. Hoses to the heater core are both warm/hot, so flow through heater core seems to be good. Also AC has same issue no cold air unless over 2,000 rpm. Is this the control to the blend door? Are they operated by vacuum and with a leak, need higher vacuum to operate?

'96 civic 180k miles. Just had timing belt replaced but has been clicking when cold so mechanic checked & adjusted valves. Still clicks on startup until warm, less than 5 minutes, as it has for the last year or more. What could be the problem?

I have a '03 Civic DX 5 speed. It has 128000 miles on it. I've notice now that it is getting colder, my engine ticks when it is warm - I can hear it at idle and low rpms, but not at higher rpms. It sounds perfect when it's cold, but once it is warm, it has a "tic-a-tic-a-tic-a-tica..." sound. Tom and Ray talked about a Dodge Dakota that made the same sound when the engine was cold (about 8 episodes ago). So what does it mean if it only does it when warm?

Nothing will blow out from vents, with heat or AC. I checked the fuse under the hood and that had continuity, I checked the 7.5 fuse under the dash and that was fine. I also replaced the blower motor resistor and the blower motor with brand new ones. Also used a test light to make sure power was getting to the resistor and motor and that is all good.

Two years ago, I purchased a 1998 Honda Accord LX from a local dealer. I've had very few issues with it. However, shortly after I moved from Michigan to Florida, I began to notice a strange issue with my car. While the car is running and the engine is idling, I lose AC inside the car and the engine heat slowly begins to build.
The AC isn't shutting off, but instead blowing out warm air. The engine heat builds at a concerning enough rate, moving from a normal level to almost maxing out the gauge in the span of 20-30 minutes. This issue seems to auto-correct itself while the car is in motion, with the AC putting out nice, cool air and the engine heat staying at a normal level.
The car currently has about 269,000 Miles on it. I have been told the problem is likely a faulty thermostat, but I'd like a second opinion. What might be wrong with my car?

I have a 2000 Honda civic ex. A couple months ago while driving I heard a squeal and my AC was blowing hot. I just changed out my expansion valve, drier and compressor but when I hooked up my gauge my low side wouldn't build pressure and my high sat like 150. Finally the low side got to 20 and high about 200. I over filled trying to get low side right and when I did get it to 40-50 my high side would be 300 but it wouldn't hold. I emptied the system but 150 psi is somewhere in the high side and won't get out.

We have a 2010 honda Odyssey and we are experiencing some air conditioning problems. The ac went out on us about 6 months ago so we had the compressor replaced. A few weeks after that the ac would intermittently start blowing warm air. We took it back to the shop and they noted that the compressor was shutting off for some reason. They replaced the compressor again, but we are still experiencing the same problem. It will just start blowing warm air for about 15-20 minutes then it will start blowing cold again. This will happen about once every 2-3 days. We replaced the relay, but that didn't work. They have checked for leaks, recharged the compressor and checked the freon and still nothing.

I have a 2006 honda civic lx and the air conditioner works fine when i first start the car.
However, after driving for 15-30 minutes the air conditioner starts blowing progressively warmer air, until it starts blowing warm (or even hot) air. this seems to happen when the engine gets hot.
One particular day it started raining, and suddenly the cold air kicked back in.
I took it to the dealer and they said i needed a compressor and coil for a grand total of $800. i took it for a free a/c inspection, and he said the problem might be electrical, but a visual inspection wasn't enough to figure out the problem.

My son's Honda Civic keeps periodically blowing the #4 fuse under the dash (alternator). He replaced the VSS and had the alternator tested but it still happens.
At one point the fuse would blow as soon as you turned the key to ignition but I traced that down to a shorted wiper motor which I replaced and that solved the immediate fuse blowing. BTW according to all documentation I have, the wiper motor is not supposed to be on fuse #4 so perhaps the under dash fuse box has issues.
Looking for a schematic for the under dash fuse box? I have the 01-02 service manual which has wiring diagrams that reference specific fuses but I can't found one for the box itself. Are there relays in that box or is it just wiring from fuse slots to the many connectors?

I have a 2002 Civic LX. A/C worked until a few months ago. It would stay on for about ten minutes and then stopping blowing cold air; it would come back on and then go off again at it's own whim. Bought it to local Goodyear - told them the problem - they charged me about $130 to evacuate and recharge, looked for leafs but told me they saw no problems with the A/C, the condenser was fine, etc. A few days later, same problems started. Runs great for about ten minutes and then does its own thing.

My ex-wife has a 2008 Prius. When trying to get heat, either using Auto A/C or manual, the display panel shows that only the floor vents are open. However, forced air is flowing from the upper vents on the dash. The air from these vents is not warmed. It seems to be unheated outside air. It's unclear whether this is a new problem, since the owner doesn't know if this behavior has been there since she bought the car. She does report that the car has always taken a long time to get comfortable in winter.
