When I turn the temperature control **** to max cold. The heater control valve goes all the way to the top and cold air blows. When I adjust the temperature off of "max". Even by just one degree. The heater control valve goes all the way to the bottom and hot air blows. So it seems that it is either all up or all down. I assume it should vary to allow cooler or warmer temperatures to come through heater core. I guess the heater control valve is ok and the control cable is ok. So is my problem the temperature control electronic parts are something different?
have the same problem?
