This is the newer body style with the 5.3 engine.
I know the problem is either the control in the dash, or some stupid little electric operated door under the dash that is not letting the heat come through for the defrost/floor heat,etc.
The rear heat works fine, but we REALLY need a defroster
Has anyone else had the same problem that can point me in the right direction to what the fix is, and parts cost?
Don't forget to tell me if the whole damn dash has to come out to get to the guilty culprit.
Thanks in advance.
