Is my dual zone head unit bad?
I searched and didnt come up with any answers. I have a 97 C5 the ac will not come on until I change the fan setting to max wait until the exterior temp comes on display then I have to push the fan button again,also the auto setting doesnt work. I wasnt sure if there some sort of relay. If the head unit is bad can it be replaced with the 2001 or newer version? Thanks in advance!
