02 Trailblazer LTZ wacky digital climate control
Hi Guys,
I just picked up an 02 Trailblazer to drive during the winter while my GTO hibernates.
There is a strange issue with the digital climate control. It turns itself on to either the AC or heat and the temp starts going up or down by itself, if I turn the hvac off, it comes back on by itself.
I tried searching but could not find anything similar. I'm wondering if there is any way to troubleshoot before just replacing the HVAC control unit.
Thanks,
