Default Re: Need help on HVAC schematics

Typically its a 1 hour charge for a module reflash with no guarentee that will fix it. Like easyed said, bit of a pain to change it out. Easiest way i have found is to remove the upper dash panel and you can access it from there. Not a terrible job just will take some time if you dont have much experience with gm trim panels.
