2002 Grand Prix Blend Door
I have a problem similar to what has been posted and discussed here.
When having the heat blowing I sometimes get cold air out the drivers side while heat out of the passenger side. I can hear the actuator changing but it does not stay in one position, it seems to fluctuate and then mostly stay on the cold setting. Is there a way to test the actuator before replacing it? It is weird that it changes but will not stay in one position.
I am not sure if it is a problem with the actuator or the control unit.
Thank you in advance...
