Hi Everyone, This is my first post, I have a 103K 2002 trailblazer, since I got this truck there is something that always bothered me and no mechanic or electric tech could figure out the following : When I turn the AC on at 1-4 speed the ac wont start and only a few seconds after the...

I have an '03 TB with 85k, when I park the car in the sun and it gets hot the a/c will blow out of the floor vents for about 10 minutes. When the interior or the space behind the dash cools a little the vents on the center of the dash will come on. I have an LTZ with the automatic control...

The front row cabin ac system has problems working. I would turn on the air and the vents facing the seats won't blow out air. the vents for the defrosters will though. The middle row AC system works perfect tho. anyone have any similar issues or any ideas on what it may be? also if I'm just...

Hi ya'll! I'm new to this thread but I decided to join because I always seem to find some helpful threads on here. I recently bought a 2006 Envoy Denali, sharp truck and I love it! Lately I have been experiencing some issues with my air conditioning which really sucks because it's been in the...

Hey everyone. I have a 06 Trailblazer ls ext with around 79000 miles on it, and I was driving around the other day and the heat and air conditioning switch stopped working (0-5). I tried playing around with what numbers it will work on and it has only worked on 0, 1, and 2. Before this problem...

I charged my Trailblazer once this year, and it’s not working again… I replaced the low pressure cutoff, as I have heard this valve is a weak link, and it is cheap and easy to replace. When I took off the cap to put the new valve on, it looked as though one of the Schrader valves was leaking...

I live in Arizona where it can get warm and hot. Recently I noticed that the A/C is not getting cold and barely cool. The A/C seems to be cooler in the morning when the temperature is not as warm. But once it warms up, the A/C is really no relief. I noticed when I was in the vehicle that the...

Hey there, I'm kind of new to this forum. I've been looking for old threads with no look of a similar issue... I have a 2002 Envoy SLT. When I turn on the air conditioning, it runs cold for about 20-30 minutes then starts blowing hot air. This happens whether I'm in town or driving on the...
