I have the same problem. The fan motor is ok, i think it may be the fan speed controler (ATC). I need to find it so i can test it.

I had taken my 2006 trailblazer in for new tires, belts, brake fluid flush ect....when my car was returned to me, I had no heating/cooling and my display was not working. I questioned the service tech. he said my control panel had failed. What could have happened to this while in for service? I had no problem with my heating and colling prior to taking it in for servcie. Could it be not working for any other reason then failure? Should I hold the shop liable?

#94 of 97 2003 TB EXT AC Fan Stays ON
Jul 01, 2012 (3:42 pm)
I recently installed a new AC controller in my 2003 TB EXT. The front AC fan stays ON after I have shutdown the TB, even when I take the keys off. This situation does not always happen. In fact, when I took it to the dealer the fan would shut down after the unit was shut down and keys removed. Furtunately, I had to come back to check on the tail lights as the third brake light failed, and then the AC kept on after the unit was shut down.
The dealer took the unit in and couldn't figure out why this was happening. Later in the day, they called and said this was NORMAL as it was an upgrade in the programming of the AC system which would keep the AC fan on (in low speed) after the unit was shut down to reduce humidity in the system.
Anyone heard of this before or have seen this happen?
Do you believe the dealer's explanation?
I'm very concerned this would drain my battery or ever worse cause an electrical fire while I'm away.

Has anyone had any issues with their air conditioning line that runs from the front of the car all the way to the back. The dealership did work on the half recalled gas tank part the one they paid half and we paid the other half. They dropped the tank to do this and now I have a leak in the air conditioning line. They say it was rubbing on the frame but I think they did something wrong. This is going to cost over $500.00 to fix becuase of where the leak is.
Oh and the gas tank piece didn't even fix the gague now they are saying it is my instrument panel and that is $400.00 so I am just keeping track of my miles and that is a pain!!!
#97 of 97 Faulty Rear hater module -passenger side- rear
Mar 25, 2013 (4:05 pm)
We have a 2003 Trailblazer. Found out that the annoying ticking sound when you first turn truck on is the rear heat module.
How do I get to it and how do I replace it??
The ticking lasts for about 2 minutes then stops. Drives us nuts!!!
