My avalanche ac is not working correctly. The ac is not cold at all and blows out hot air when it stops. I refilled it with freon and it still doesn't get any colder. What might be the problem? And also even though I turn the ac up high, it doesn't blow very hard. (I used the gauge when refilling freon, so no overfilled).
View 3 RepliesI have a 2002 Avalanche 2500 4w drive with the 8.1L engine. The problem is that it is leaking oil, but only after a long drive. Plus the leak happens like a spray after the car has been sitting for more than 20 minutes. The oil is leaking from IN FRONT of the driver's side front tire and I can't see any oil up on the car. The oil leak only leaks for a short time and then stops until the next long drive. The truck has 118,000 miles.
View 3 RepliesI have an 02 Avalanche 1500 4wd z71. It has 173000 miles. Noticed a clunking noise under driver side when slowly taking off. If I floor it there is no sound at all. This only happens when vehicle is on 2wd mode. If I put it on auto 4wd there is no more clunking. The noise sound like two pcs of bare metal are hitting each other. What this could be.
View 6 Repliesi am having some big difficulties with my car i own a 2002 Lincoln LS v-8, has about 118,000 miles on it. when i bought the car USED the heater or ac didn't blow at all we fixed that all it was a fuse. But know that it is winter time the thing is my cars heater blowsn out cold air. ive noticed some times heat blows a little from the passenger side but not the driver and then if it does get warm (my car) its takes for ever. Know i dont really have a problem with the defrost becaseu in the mornings my windows are defrosted after like 20min. ive been reading alot about DCCV and i want to think thats the problem but i really dont know.
View 2 Repliesi recently purchased a 2007 Chevy Avalanche 4WD (75K miles) and much to my chagrin, in the first week, i detected a noise that has steadily become worse. the dealership (a Chevrolet dealer) has not been able to determine the cause. I've had it back four times already. The noise always occurs between 45-60mph (not rpm-related) there is a groaning sound and it is accompanied by a vibration in the steering wheel. it is especially notcieable when going around turns in the road at these speeds.
The dealer said it might be related to the alternative fuel management (DOD), but i deactivated the AFM and the noise is still there. I suspected wheel hubs but they checked and said the hubs are fine. The other day as i heard the noise i dropped it out of overdrive down into "3" and the noise suddenly disappearred. All gear shifts are fine, but this was somewhat alarming. I am beginning to think this might be related to the transfer case or front differential? maybe this would be good for "Stump the Chump" ?
My 2003 Avalanche (5.3L) suddenly started losing oil, 2 quarts since my last oil change (3,000 mi). There is no evidence of it leaking and no apparent smoking, so when I went to get my oil changed today I was telling my mechanic about it. They couldn't find any evidence of a leak either. Then when the pulled the fill plug on the transfer case fluid poured out, a lot of fluid. They are the only ones that service this vehicle so we were puzzled as to how it could be overfilled, especially by so much. Then I got to thinking, the engine has lost about two quarts of oil and the transfer case has mysteriously gained a bunch, possibly two quarts. So the question is, is it possible that the engine oil is somehow moving into the transfer case?
View 19 RepliesHave a 2002 avalanche Z71. Transmission was rebuilt 33k ago. It currently shifts a little hard going from 1 to 2nd. Real problem shows up between 40 mph and 50 mph. It suddenly shifts into overdrive which drops the engine rpm waaay down and starts lugging the engine.
Took it back to the guys who did the rebuild. They drove it around and noticed that the computer reported no codes. They claimed it was the TPS and said to replace it. I did. Problem is still there.
Took it to a highly trusted mechanic. They said they think the valve body needs replacing but they don't do transmissions. The guy they recommend drove it around and he thinks it is the torque converter.
I am wondering what causes the computer to decide when it is time to shift into overdrive and I am wondering if there is some sensor that has gone whacko and needs to be replaced instead of starting to tear the transmission apart.
I have a 04 chevy avalanche, when I turn on the cold air the drivers side blows hot air and the passengers side blows the cold air.
View 3 RepliesI have a 2005 Chevrolet Avalanche with the 5.3 V-8. When one goes to start the engine it continues cranking (sometimes) after the engine starts and you let go of the key . Sometimes it only does it momentarily; sometimes you have to manually bring the key back so it stops cranking. I have gotten several opinions. Some say ignition switch in the steering column; others say starter/solenoid; others say electrical problem such as a relay. Problem is it only does it sporadically and it never does it when I take it to the shop. What the problem is ?
View 10 Replies2002 Windstar A/C problem. Blows cold in the rear but not the front. Blend door actuator in the front is operating properly. Compressor cycles on and off but not excessively. When temp levers in full warm air blows to floor but it is not warm. Compressor runs even when the A/C on/off switch is in the off position. Indicator light is off but compressor still runs. Condensate puddles on floor in rear but none in front under vehicle.
View 8 RepliesI own a 2002 Grand AM GT. With the engine temperature reading around 200, and the heat set at maximum, frequently, for about a minute, I will get nothing but cold air. At maximum heat setting, on one day, there would be hot air. Yet, at another time the air output would be lukewarm.
View 3 RepliesI have no heat in the LS at no settings. The AC runs good but does not seem to be regulated as it blows cold at any temp setting. The fan responds to settings but i still get no heat even with the AC turned off. I would like to find a diagram that shows the locations of the bleed valves to start a coolant air bleed.
View 13 RepliesWhen I turn the a/c on, sometimes the compressor engages and sometimes it does not. When it does, I feel the engine's idle change and out comes very cold air. After a few minutes or longer, no more cold air but the fan is still blowing. If I quickly turn the a/c off and then back on again this seems to jump start the compressor and poof, out comes the cool air again. Sometimes it will begin producing cool air again on its own but most of the time I have to resort to turning it off, then back on. I don't believe I have a leak because otherwise no cool air would be emitted at all or the quality of the cool air would be poor.
View 2 RepliesI don't know how the story ended with the 07 4WD Avalanche with the unidentifiable noise - he said, "The noise always occurs between 45-60mph (not rpm-related) there is a groaning sound and it is accompanied by a vibration in the steering wheel. it is especially noticeable when going around turns.."He went on to say that he checked the hubs and they were fine, and decided that he would replace the tranny. I sure hope that fixed it.I had the same problem on my 07 4WD Avi, and the hubs checked just fine, smooth as silk, with no loose play at all. But on a 1000+ mile trip just a few days later, the groaning and vibration grew worse, but only when I went around a left curve. I barely made it to my destination - the right hub failed. If it had been groaning and vibrating when turning right, it would've been the left hub. I replaced both at the same time.
View 3 RepliesI have a 2004 Chev Avalanche. Several times recently my check engine light comes on, the truck dings 3 times at me and a dash script tells me to tighten my fuel cap. I do and the light goes out within a few hours or the next day. I have changed fuel caps twice. This week the light came on, has not gone off and at least 3 time it has told me to tighten the fuel cap which I have done.

View 6 RepliesI have a 2002 Dodge Durango and the rear passenger air blows cold only - was fine last winter. Neither the passenger or the driver controls will get warm air to the rear via the overhead vents. Warm air comes out under the front seats to the rear only.
View 1 RepliesI am the proud owner of a 2002 F250 Super Duty 4x4, which has 158K miles on it. I live in South Florida and use the truck as my daily driver and also from trips up into the Blue Ridge Mountains.
Recently, I noticed that when I have the A/C on it blows nice and cold for about 15 minutes, but then the air gets really warm. I had the system checked and the Freon levels are right where they should be. A bit of experimenting reveals that if I turn off the A/C for about 10 or 15 minutes after it starts to blow warm air, the systems blows cool air as it is supposed to.
Therefore, I suspect that something is freezing under the hood and preventing the system from operating properly. Since A/C is pretty well essential for us in south Florida, this is a problem, when I have the family or customers in the truck.
I have a Buick park avenue 1998, 3.8L V6 engine. the problem is: The ac vent on the driver's side blows cold air but on the passenger side blows EXTREMELY hot air. no matter how cold or hot you set the ac it blows at the same temperature on both sides. Florida heat is setting in and my passengers are melting. I am really hopping that is not something to bad and that I can fix it myself. Tip: this started happening after i had the alternator and the battery replaced.
