My "OFF" button doesn't work on my AC/Heater Control Unit. It stays on all the time. You can adjust between low/med/high fan, and defrost, floor, etc works. It wasn't a bid deal to me but now when I start the truck the "A/C" blinks on and off for 5 minutes or more, then goes off. This happens whether or not I actually have the AC on.
Do you think this is just the electronic unit itself that is fried, or something else I should look at. I'm thinking if I buy a new electronic unit it would fix all the above.
What do you all think?
