#34 of 52 06 tblazer intermittent air conditioning by tigar

Jun 23, 2010 (6:38 pm)

I have an 06 trailblazer that the air works sometiomes usually when it's cooler. Other times the compressor is running but no air/blower at idle, when I start moving I get cold air sometimes but not maybe as powerful as it should be. When I stop at a light it stops again. Not related I don't think but I have replaced the mass airflow sensor and O2 sensor recently ( lean condition in bank one). Thought it might be a vacuum leak or hi speed blower relay. Any ideas ite 90 dewgrees here and need the air fulltime.

Hello,
 
I have a 2006 Chevy Trailblazer, I replaced the battery and now the AC will not blow cool air. I checked all the fuses is there something that I am missing?
 
The Air is blowing, and when I push the AC button it lights up, but no cool air.
 
Any Ideals
 
Thanks
Scott

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 by jnhnelson

Sep 06, 2010 (9:26 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 by walt32

Sep 29, 2010 (10:16 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?
 
Thanks,
 
Walt

#41 of 52 2004 ext blower motor by blaizer04

Oct 28, 2010 (6:04 am)

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.
