GMC Safari Repair Question
Mode door acuator replacement
Is the actuator electrical or vacumn?
it most likey is your heat /ac control panel.
I had the same problem with my 97 truck and did a search. the panel is all elctronicaly controlled and your circuit borad most likely went out. I had AC one day the nest nothing. only had control over the tem and the fan. try here for a great price for a replacement.
hope this helps Joe
