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.

#46 of 52 Blower does not work
Jul 12, 2011 (8:21 am)
We have a 2002 Chevy Trailblazer, we purchased this fresh off the lot in late 2001. We too have had problems, the speakers in the back don't work, the rear defrost has gone out twice. and now our heating and air conditioning blower stopped working 7/11/11. First we lost #1 & #2 in 2004 and a couple of months later we lost #5. So we were left with #3 & #4, well we lost those now too. It seems like this is a common problem. Does anyone have an easy fix for this?
#48 of 52 Trailblazer Air Conditioning Problem
Aug 05, 2011 (4:25 pm)
I have a 2009 TB. The amount of cold air coming out declines sugnificantly when the car is running a slow speeds (35 mph or less). However, it seems to produce a fairly good amount of cold air when the car is at 50-60 mph. I also notice a lot of condensation dripping from the metal hose on the left side of the engine compartment under the water resevior when the car is idling in the drive within 30-60 seconds of starting the car. I can't see exactly where the leak is coming from if it is even a ture leak. Before I take it in to a dealer to be ripped, I would like to know if I am look at a major problem or something more common such as a refrigent leak or bad seals. Can anyone give me some advice.

not sure about the cold air.. but i had a leak a few months ago... come to find out when you open the hood of your tb look at the left back side theres a rubber 90 degree piece that points down... usually it gets clogged and backs up into the cab.. Pull it off and use a pipe cleaner.. this worked for my 04 trailblazer

#51 of 52 Help with A/C and Heat and air
Nov 28, 2011 (1:55 am)
Have a problem that I'm hearing is more common in the 2003 chevy trailbaizer EXT. Both the heat and A/C will now only work on the 5 setting, we noticed ealrier in the summer that occasionaly the air would work only on settings three or higher, however recently the only output we now have is on setting 5. Also with the heat on regardless of the level I now have only cool or cold air being blow into the middel and rear zones. Any ideas or advice would be greatly appreciated, signed desperately seeking heat in cold OK winter.
#52 of 52 AC/Heat Vents
Aug 12, 2012 (6:16 pm)
I Just changed my battery in my 2004 LS TB, when I turned on the ignition my AC/Heat only works on defrost vents and a little from the floor vents no matter where I turn the vent control knob. When I key up to accessory I can here something humming or chattering, sounds like coming from top, center of dash. Has anyone experienced this or have any ideas on fix. I appreciate any help you can give me in this matter.
