Prius (2004-09) :: Air Conditioning Works Intermittently
May 20, 2010
2006 Prius with 58,000 miles. Drive in San Diego and Palm Springs. Earlier this year, the A/C would just cut off, maybe about once a week. The control panel indicated the A/C should be on, but absolutely no function. Drive around for 20 minutes, and all of a sudden, it would come on and work perfectly. It is starting to happen on a daily basis now...sometimes it won't work from start, other times it just cuts out while driving. I can park the car and shut the car off with the A/C working, then come back 30 minutes, and no A/C. It doesn't seem to matter which setting is selected. The control panel accepts all commands, but no function changes when the A/C has shut itself off. Loose connection somewhere? It works about 90% of the time, and blows very cold. When it shuts itself off, no air passes through the vents at all.

I had a question about the light in the gear box/shifter on the dash. Mine seems to work occasionally. Sometimes when I shift into a D or B it'll pop on. Lately it's stopped, I was thinking maybe I have a short in it or it needs to be replaced.
Upon searching through the forums it appears I'd have to replace the whole shift mechanism, is this correct?

Recently my truck is only blowing heat or air conditioning on full blast in my 2004 Ford F-150 (New style, not heritage).
Level 1, 2, or 3 is exactly the same and blows almost nothing, then if I switch it to 4 it is full power.
I just don't know what exactly I will need to change. I know it would be a resistor pack somewhere that probably failed, I just don't know where it would be.
Do I just need a new control switch, or do I need a new heater fan?

The air conditioning in my 2002 Chevy Trailblazer works but never gets really cold. What is the best course of action to get it working better? A do it yourself kit or an auto repair shop?

Friend of mine said that the air conditioning on her 2001 Ford Explorer only works when her car is in idle. She said that when she steps on the gas the fan continues to work but doesn't blow cold air. If she stops at a stop sign it works... and so on.
She has taken it to a shop that specializes in air conditioning and he checked and cleaned off a few connections (whatever that means) and thought that would do it but it didn't. She is going to go back this weekend.
I told her that I would think that a specialist would see the idle/drive issue as a good clue as to what the problem is.

First it wouldn't turn on, at times now it at times won't work even though the light is on, on the dash. At other times it works as expected. I dun think it's the 12V battery, because when only the center console is on in diagnostics the battery reads 12.2-12.4 and 14.5 + when the engine is on.

2004 Chevrolet Tahoe that has the dual climate control features. Some days the A/C blows cold on one side and hot on the other with it set on the coldest setting. Another day it blows cold on both. Then you guessed it a few days later it goes back to blowing hot on one side and cold on the other.

I have a 2006 F-150 S/Crew and I seem to have the same intermittant odometer problem as many of the folks in that 1999-2003 group. The odometer comes and goes, flashes intermittantly and sometimes doesn't work for days.
Can it be repaired in the same fashion as those older units? The dealer is more than willing to sell me a new cluster (obviously). They say that there is "no way to possibly repair those odometer problems and we see them all the time."

I've been noticing some issues with the touchscreen on my 2007 Gen2. Sometimes when I touch the screen, the unit doesn't respond. Other times, I need to touch slightly above the area I am supposed to touch in order to get the correct response. It doesn't happen all the time, but more than just occasionally. I asked my local dealership about it and they say the screen probably needs to be replaced. I've also heard that perhaps recalibrating the screen could work.

The AC on our '04 RX330 has started acting up. Refrigerant level is fine. When the system works it's ice cold. It'll run more often than not, but occasionally the AC compressor just won't kick on. I searched the forum and found issues in other toyotas and lexus models with the magnetic clutch relay but for the life of me I can't find where that is on the RX. I also saw reference to an AC "servo" in another thread. What controls the AC compressor and what to check?

I'm having problems with the auto dimmer mirror in my camry 2004, it work some times but most of the time didn't work and is really difficult to use it during the night because the lights from cars behind shine directly in my eyes. The compass in the mirror works all the time but the dimmer not, I notice that the green light in the bottom of the mirror is off most of the time.

2005 Dodge Ram 1500 SLT Big Horn, 5.8L V8 Hemi my air conditioning only works when I'm driving forward, and does not work at all any more when I'm sitting still at an idle. this is a new problem. the A/C has worked like a champ for the past year (since I started using this vehicle). I even refilled it by myself last summer, with no issues until now. when it is at idle, I hear a clicking coming from the A/C system, and the RPM's arch a little bit. then it clicks again, and the RPM's go back down. it does this 2-3 times a minute. also when at idle, the air is VERY HOT, considerably warmer than the outside air. also, I have a pressure gauge for the A/C system (came with the refill kit last summer) and it says that the system is holding too much pressure. it suggests a possible mechanical problem.

I have a 2003 Prius that I have had about 4 years. It has under 80,000 miles on it and I have the Ecrostech Scanner which I have had for about 3 years. For the time I have had the Ecrostech I have noticed times when the regenerative braking was not working when I would depress the brake pedal. I understand the regen does not work from about 7 mph and below but my system often does not work even when it is above that speed. I have not been able to force it into regen. It seems to have a mind of its own as in perhaps a faulty ecu.

I just purchased the car a few weeks ago. Horn doesn't work till I press about a dozen times and "get lucky".. Once it hits once I can usually beep about 4 times before losing it. I checked the fuse, looks fine. Haven't found the relay yet.
I suspect it is something in the switching/contacts/ground in the steering column. What I may need to replace in steering column?

My a/c has been cutting out (warm air coming through) intermittently. If I turn it off for a few minutes, it generally comes through nice and cold again; sometimes the cold lasts for a while and sometimes not. It can happen after just 10 minutes of driving 45 mph, or after 1 hour of driving 70 mph.My mechanic drained the system and re-charged it, but that hasn't worked - although he is a terrific diagnostic mechanic, he is puzzled.

My 2006 F150 was purchased by me in early 2009 with about 28,000 miles on it. It's an XLT crew cab 4X4 with the 5.4. Stock except for a leveling kit and an aftermarket head unit. It currently has about 59,000 miles and has been babied since I purchased it. About 3 years ago I started noting some issues:
A. Oil pressure dummy gauge is all over the place. Some times it will show no oil pressure. Other times it is all the way to the highest mark. Other times the needle has gone 180 degrees past where normal is and is actualy pointing straight down towards the floor.
B. Recently my alternator dummy gauge has started doing the same thing as my oil pressure gauge.
C. The backlight behind my odometer works intermittently, but mostly not at all.
D. My dome light will flicker when first turned on. It doesn't matter which door is opened or if the override switch it turned on. It takes several seconds to come on and will flicker like there is a poor connection somewhere, but stays on once its on.
E. Blower fan will occasionally stop blowing. Once the climate control switch is turned to off, then back to on it resumes working. This doesn't happen often, but does occasionally.
Fortunately, the truck has not left me stranded and I want to keep it that way. We are getting ready to sale my wife's Toyota and this will become her daily driver. I want to take care of any issues before she starts driving it. Are these all separate issues or is there one common issue which could be causing them all?

I just found out that the air conditioning compressor is broke in my 2006 prius and its going to cost $1800 to fix it.. I am not in the loop here but that seems ridiculously high. I mean i save money at the pump but all that money just went out the door if i get this repaired. I am really contemplating trading the car in rather than deal with that expense..

I have a 2008 that I bought brand new, it now has about 60,000 miles on it and the air conditioning is not cutting it in the Chicago summer. Would it now be time to have it recharged? Is there modification to make it more powerful?

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.

2002 Honda Civic LX
Maybe a year ago I started having problems with air conditioning. The hot air part works fine, no problem whatsoever. But the cold air thing doesn't work as it used to. It's not the fan - the fan blows enough air for a little storm, it's just not cold enough.
First time I noticed, it just stopped making cold air for maybe 15 minutes. Air was coming in at ambient temperature, not even a degree cooler than that. Then it started working again. Ever since then I've had intermittent failures like this, and then it would start working again. It's not a change in flow, it's a change in temperature.
Second symptom - even when it does work, it seems inconstant. Before, I could just set it and forget. Now sometimes it seems more fidgety, and I have to keep turning the button when it starts acting up.
Third symptom - it doesn't seem to make any cold air at all when the engine is idle. The engine must run at normal cruise speed to get any cold air out of it. Before, it was slow to make cold air when idle, I had to wait a while, but eventually it would start to make cold air. Nowadays, if I'm coasting downhill, there's no cold air at all.
I'm worried that one day it will stop working altogether. Plus, it's not fun when it's hot outside and this thing decides to take a vacation. I didn't care about it in winter, because the hot air works fine, but now that summer is knocking at the door, this is suddenly a problem.
What might have gone wrong? Is it something that's easy to fix at home, or should I take it to the mechanic?
