I have a 2003 Chevy TrailBlazer V8. The air condition cuts out every now and then. When it works, it works well, When it cuts out the air is ambient or hotter. I contact a mechanic and they said it is not freon, but maybe the electronically controlled doors in the dash. One door is about $300 and the other is $500. Could it me something else or does sound about right?

I'd have it looked at for another opinion. When it "cuts out" is the compressor running?

I think the compressor is running. I happens when I am driving so it is hard to tell.
#39 of 52 2005 Trailblazer blower wiring
Sep 06, 2010 (8:26 am)
Blower stopped working but compressor still works fine. Went to install a new blower and found that I had a wiring problem: Burnt ground between motor and resistor. Found several places on the wire that had been hot and had damage but only one place where the wire was burnt in two. I replaced the ground and it lasted for about a week. Question: what is causing the ground wire to get so hot? Any suggestions?
#40 of 52 Tuning folk-like sound heard when AC is on
Sep 29, 2010 (9:16 am)
I have a 05 chevy trail blazer whereby I hear a resonating, tuning folk-like sound coming from the right, passenger side dash of the vehicle. This sound is very low and intermittent. It is heard when the AC is on. The blower blows cold air after about 3 to 5 minutes of being turned on.
Can anyone help me troubleshoot this problem?

a couple of months ago the 5 setting on my air-conditioner and defroster did not work. then all of the sudden it started working. 2 months later i have a horrible smell coming from the vents when i have the heat/defrosters on. it smells like burning plastic or electrical. what would be the cause of this?

A burned or burning resistor or resistive strip on the blower motor resisitor assembly would be my guess.

I have an '04 Trailblazer. My #5 setting on my air-conditioner works sometimes and sometimes it don't. Also my air only blows out the defrost vents and the floor vents. Then also when my A/C is on my car has a tremble/idle problem, especially when at a stop light/stop sign. It sometimes turn off. I took my truck in yesterday to an auto shop they could not repair the problem with the #5 setting because it was working at that time so they couldn't diagnose the problem. But the tremble/idle problem they said it the throttle bore that needed cleaning. They said it got coking (not sure if I spelled that right but it sounds like that lol) and that sticks to the throttle bore and it restricts air. And the air blowing out some of the vents problem was due to a bad actuator. They said there were several actuators (IDK) but the actuator in vent for mode applications was bad. Every problem I have had I came on this forum and it shows people entering tons of problem with the same issue. I have even seen reviews from people that has '07 or higher chevy models and they are having these problems and it is ridiculous. I will NEVER buy another chevy/GMC vehicle again. These forums have really helped me to get to the bottom of some of my problems so I could go to a dealership like I know what was going on. But this is ridiculous and chevy does not do a recall on any of this.

It is probably your after blower. Basically it is a factory default that helps dry our any condensation in you AC vents. It's a good thing, but I think it has contributed to the early demise of my blower resistor.
#45 of 52 04 trail blazer only blows cold air on the floor

04 LT electronic AC & Heat controller. Regardless of mode selected air conditioning only comes out floor vents.
