    If my Freon leaked down would that stop the heat from working? A little back story. About 2 weeks ago driving along with a/c on. Had a foul smell inside the passenger compartment, after a minute or two the air stopped. I'm going to guess that the smell was a Freon leak, didn't smell electrical...

    The blower motor in my 2005 trailblazer quit working. I went through and found that the harness was cooked on one wire and the resistor was shot so I went to the dealer and bought a new one. I went to the dealer because I found many different kinds out there and they confused me a bit. The...

    Noticed a strange issue that's happened a few times in the last couple of weeks. I took the Rainier on a long trip, and noticed after an hour or so, the heater started blowing cold. Didn't matter what I did with the (digital) controller's knobs, cold at all temp settings. The next morning I...

    I have no heat or a/c in the rear of my '05 EXT Trailblazer.

    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 recently purchased my 03 Trailblazer EXT 4.2L. The front heat and air did not work from day one. We survived summer with the HVAC 2 and open windows/sunroof. The many posts I have read seem to indicate that the problem is likely a dead blower or blower resistor module or faulty wiring. The...

    My 03 ext climate control unit will not function at all, whether its on 1-5 manual speeds or on auto climate control. It stopped working few days ago and since then nothing has worked except for one instance where the fan kicked on full blast for a min or so but then stopped again. I have read...

    I've been looking around for quite a while and cannot find the issue that i have. the issue is that my rear heat takes forever to get warm. example it's 30 degrees outside and after 5 minutes of driving i can turn on the front heat and it's blowing warm air. so i'll turn on the rear heat and...
