2004 Trailblazer LS 4x4, 4.2L:, 2016 ATS-V, 2014 CTS-V Wagon, 2018 Audi A7
I have searched more than once, thank you. My 2004 TB LS has an HVAC control for the back seat and is located on the rear of the front console. Every time I start the car I have to manually turn on the rear air. Is there a way to defeat this so it turns on automatically whenever I start the car?
