How to replace HVAC Control Module 2002-2009 Chevrolet Trailblazer

Excellent job! 4 years ago I went through that and replaced all the bulbs for illuminating the HVAC module and the instrument cluster. Now I have cold solder on A/C cycle switch lead somewhere in the module. Hopefully I can bd it and fix it once I take it out again.

Good video, though I can I be sure the problem is with the Control Mod versus the fan control mod under the glove box. Symptom is the fan only works on high speed #5, 1-4 wont work.. I am not sure which to replace. The fan control mod under glovebox is much easier than than this climate control mod in this video. Thanks in advance !

Excellent job

So should I do this because my air isn’t blowing out those front vents only defrost and floor since we got a new battery

I wonder if it's possible to swap out the auto HVAC controls that I have in my '09 trailblazer and put in the manual ones like these. Reason being is I can't stand the auto ones.

Gracias 👌👌👌

very good 🙂😊

I changed the battery on my trailblazer, now one of the actuators clicks about 100 times every time I start the car. Is there a reset? Any ideas?

2009 envoy .yeap that's what I have and I'm lucky it just a winter rat. Thanks mister . PEACE

Holy crap
