My 1992 GMC Sonoma Blower control overheats and smokes in the vent position. It does not happen in any other position. I have checked all wiring for shorts and connection problems, vacum pods are all working, and physically checked the swith internally. I happens with the temparture control in heat or cool position. With the switch in the on position "without" the engine running it operates normally. This only happens if the engine is running.
have the same problem?
