    Hello, I have a 2003 TB. The freon is full and the compressor is turning on and off. However, when I switch from heat to a/c, the only thing i get is heat. It does not get cold at all. I was told by the GM dealer mech that the actuator is bad. Can I replace this or is this something that the...

    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 have a 2003 TB. After driving about 10 minutes, it started slowing down. I couldn't get above 30 mph and that was with the pedal pressed down fully. Found out my brakes were locking up during driving. We unhooked the ABS system and it still happens. When it happens, I turn the truck off...

    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...

    I am a novice mechanic, just been working on my cars. I just bought an 03 trailblazer with 86K miles. I bought it on a cold day so I didn't notice the AC wasn't working until later. I have the sliders (manual control) for the AC. I put two 24 oz of r134a in. When I was filling it the AC...

    Searched for about an hour for this issue, but none found. My A/C works great, but when I set it to 1 (Lowest Setting), it doesn't work at all. FUSE? SWITCH? DIRTY CONTACT? SEPERATE BLOWER? 2003 Trailblazer LT 4x4 SWB 4.2

    I just had my fan clutch replaced this morning because it went bad. As I left the shop I kicked on the A/C and rolled up the windows. I immediately saw the RPm gauge jump to almost 0 RPM's, then it went back up to normal. I sat there for a bit and it continued to do this till I shut off the A/c...

    ok, So I have an 04 engine after the plunge (Continue to scroll down after the image).. For those who haven't already seen this. Yet remember I have a 2005 model. I took it into Chevy about a few months ago about not having A/c - even after recharging it twice. I also told them that after...

    I noticed this recently. When my air conditoning is on something under my hood makes a tick tick tick noise all the time but when I turn it off it stops. The air works fine I just know its not normal for a car to do this. Any solutions? :crazy:

    First off, I have to say, I have been looking @ this site for a few days & it has been very VERY informative and helped me learn a few things.. I bought my 2004 GMC Envoy used almost 3 years ago, and have had nothing but problems with it, it seems. The only instrument on my dash that works is my...

    Bought a 2005 ENVOY XL with Manual A/C front and rear. The bad stuff has now hit the fan. Was told (by the dealer from whom I bought the car a year ago) that A/C Compressor is dead and that orifice would have to be replace along with compressor. 1. Are there 2 orifices in this vehicle with the...

    OK, so I've got the much talked about 'whine' and I think it's the A/C clutch. The only time it temporarily stops is when I turn on the A/C, and only when I am driving slowly. I can hear the whine cutting in and out, but I'm hoping I don't have to replace the whole compressor. Anyone else...
