Yukon :: 2005 XL AC Started Blowing Hot Air Even Though Set To Cold
May 22, 2011
I have a 2005 Yukon XL. In Oct 2010, my front A/C started blowing hot air even though it was set to cold. Nothing has happened since then, except that about a month ago, the A/C in the front stopped working but the A/C in the back still works great. The one in the front works when it wants to (once or twice in a week) and when it does, there is cold air coming out of it. We live in FL so it is getting pretty hot to not have A/C and we are going on vacation soon. What can be causing my A/C to work like this?

My A/C wasn't working (blowing hot air instead of cold), so I had some repairs done. First I was told it was some sort of bracket, replaced that. Then the guy told me it was the compressor, replaced that. About $1K later, he returned the vehicle to me, and the A/C worked about one hour, and even then wasn't super cold. I have since had the freon level checked and there are no leaks, everything seems to be OK, it just doesn't cool.

I have a 1988 Toyota Camry LE V6. And recently the heater just started blowing ice cold while on the hot setting.

Chrysler Town and Country. The engine warms up just fine regardless of my speed or throttle position, but the cabin heater has started blowing cold air when I back off or sit at idle. It may be relevant that we hear a lot of gurgling in the dash soon after starting the engine.

Here's what I have. 02 X 7.3L 4x4.
Heater will work fine. Then out of nowhere just blow cold. I can turn it off then back on it'll blow hot for 1 minute or 20 minutes. Then out of nowhere blow cold again. It doesn't matter if I'm highway driving or city driving.
I'm kinda thinking it may be the door in the duct that's just closing. I real don't know.

I have an 05 prius that has been a great car 193,000 miles with no issues, until now. AC started blowing warm air so took it to mechanic who replaced the compressor. Blew cold for a day and started blowing warm again. Took it back to mechanic replaced the evaporator. Same thing blew cold for a day and then warm air next day.
Mechanic told me to take it to Toyota to get it looked at and they said 3 way coolant valve so we replaced that and still blowing warm air. Took it back to Toyota for the second time and they said it was a bad compressor so we replaced that and still no cold air. No AC in Florida summer is getting old fast need to get this fixed.

I bought my 2005 prius used 6 months ago, all the mechanics work fine except my AC which started going in June.
Over 2 weeks it started blowing less, eventually nothing. Used the refrigerant (the correct one with no oil) and filled to around 33 every other day for a while and it would work great. Finally went to dealership 3 weeks ago, paid 140 and they replaced one valve (expansion valve? cannot remember) and filled it up and it worked for 1 week. They said a previous owner had dye put in and they saw the dye there.
Brought it back when I thought it was starting to go again and they said they saw a small amount of dye leaking in the evaporator but it would last 2 months minimum (obviously didn't). I was quoted 1400 for evaporator replacement.

2005 santa fe a/c not working. Started out barely blowing out cool air. it was cool but we were still hot in car... kept adding freon but it barely worked. One day we heard a strange winding noise and have had no a/c at all since then. Don't want to buy a whole new compressor if it could just be a switch or something.. I see there are so many a/c parts. Is there any way to tell if we need a new compressor ?

2005 Isuzu Ascender 6cyl--auto-- all power--2 wheel dr-- Air cond blows very little air that is only slightly cooler than the outside temp. This only happens during hot weather( 90 Fahrenheit or higher ) after highway driving for extended periods of time, usually after a few hours. It works as it should during any other conditions. After letting everything cool down, it works properly. The dealer says they cannot get it to duplicate this action and therefor says there is nothing wrong with it. I first noticed this at about 50,000 miles because that was my first trip in it. It now has 70,000 miles.

Was driving my truck I have a 97 f150 4x4 4.6L, btw. The heater started blowing cold air and I looked at the temp gauge but it was showing lower than it normally does and then, after a couple of miles or so I looked at the temp gauge again. By this time I was in my driveway. And it was overheating it might have been that way before I looked at the temp gauge again. But any way I opened the hood didn't see any leaks, all my hoses were hot except the top heater hose. Also checked the oil it was full and coolant was too, what this could be? Sounds like a t-stat to me? But could be worse. Also forgot to mention that the oil had no signs of water in there nor the expansion tank cap !

I have this problem for some time already. Most of the time my AC works great - blowing cold air as it should. But sometimes it starts blowing "normal" air instead of cold. To fix that I have to turn OFF and then ON the AC again by pressing the AC button.

My Prius has 198K, runs great and has been trouble free. This week it started acting up. The AC will run for a few minutes, blowing very cold, then will blow warm air for a period of time, perhaps 10 minutes, then will blow cold again for a few minutes. It will repeat this several times, then will blow cold until the end of the trip, about another 30 minutes.

So roughly 2 months ago my ac wasnt blowing cold anymore and it was the evaporator, so i got a new one put in and recharged and it blows 50 degrees or colder now and it still blew that cold today. But today i heard a noise coming from the engine, so i inspected it and saw the compressor was turning on and off which it was doing right before i got it fixed 2 months ago, so I know its not the compressor but i know that's probably gonna go soon to. now its getting to winter so I don't need the ac.
Everything else is working perfect never had any problems with the car other then the ac, it does get used a lot cause but it never gets pushed passed level 2 out of 4. it has 90k on it and i was wondering if this is a major repair to just let it go and sell it for a reasonable price and pick up another car? or just fix it and hope another problem does not arise in 2 months. Like i said ive never had any problems with it before other then the ac. it still runs great and i can still floor it and she responds almost like new.

My 05 has always had good air conditioning front and back but around three weeks ago it quit blowing cold. I found all the 134 had leaked out through a pin hole in the aluminum line that runs down the back of the engine to the rear ac unit. I removed the line and brazed the pin hole. So I reinstalled the line, put a vacume on the system for 20 mins then let it sit for another 20 to make sure I had no leaks. All seemed good so I re charged the system. Now my front blows nice and cold but the rear is warm?
My pressures at idle are around 40psi low side and 200ish on the high side when the engine is warmed up and the ambeint temp is around 74 f. If I turn it to the warmest setting for the rear it gets noticeably hotter so I'm thinking the blend door is working properly?? I've read that the thermal expansion valves can give some trouble so I pulled the jack and cubby out to gain access to it. I tried tapping on it with no gains. Also the top left line seems to be pretty cold coming out of it too the evaporator but the line coming out of the evap is room temp. I was very careful not to let any junk get into the lines when they were apart for the line repair but I'm thinking maybe some junk has plugged up the TXV?

My problems in my ac begin last year around Summer. My ac was blowing hot and not cold and once it even blew some kind of smoke out of the vents. It only did that once and hasn't since. I went to good year and put some freon in the car. And it started to blow cold again and I was good for a while. Well I didn't need the cold air for the last few months till the heat started up again.

I have a 2002 GMC Yukon with 195,000 miles. The oil pan is now leaking and it needs a new gasket. It has 40psi oil pressure at idle. The lifters knock when first started. Should I replace the oil pump when the pan is pulled to replace the gasket? What else should I change while the pan is off with this high mileage vehicle?

Alright, dodge grand caravan 3.8. Year: 05' ... Just broke 100k miles on this thing, last time i changed the plugs i noticed plug 2 had oil all down in it. I completely forgot about the problem cause i got side tracked with bad sway bar bushings. Anyways, what is the cause of the oil leakage? It has gotten so bad that I am blowing smoke when its cold, even is warm weather. There is also caked on oil and dirt on a lot of the parts down the front left side of the motor. Blown head gasket? Bad valve cover gasket? I want the best way to approach this . The smoke is white, but not enough smoke to be a completely blown head gasket.

The horn in my car started to sound like if it was going to catch a cold then it stopped sounding, however if I press the panic button in the keychain it does sound perfect. Where and what should I look for. Is it a relay, the spring contact on the steering wheel?

I've got a 1999 Yukon with a new (rebuilt) engine ad a new (rebuilt) tranny, both only about 3-4 years old. Within the last 2 years it has started to 'snap' to the left or right when I move the wheel just slightly. My husband tightened the steering and that worked a little but it still does it. It's pretty scary when your on the highway and go to adjust your lane placement and the wheel jerks out of your hand in the direction you're turning! Also, the truck has also developed a nasty habit it simply shutting down while I'm driving. The last time it did it I was on the freeway doing 65! It always starts right back up but I'm worried that one of these days it won't and I'll find myself in a real pickle! Nobody I've talked to (including mechanics!!!!) seem to know what these problems are.

My 2005 Accord V-6 makes a howling (actually a loud whine) when started in very cold weather (e.g., below 25 degrees). The sound goes a way after a few miles driving. It appears to come from a small "pump" looking thing at the top and on the left (facing the car) of the engine, which is attached to a pulley. My mechanic - although he did not actually hear it - says it's nothing to worry about; it's just the cold.

I have a 2005 yukon xl with 55000 miles and it makes a squeaking noise when accelerating. When u let off the gas it goes away. If u r in the driveway and let it roll it will make it. It doesn't do it when u put it up on jack stands and have all 4 wheels off the ground. It sounds like it is coming from the middle of the vehicle.
