Does anyone know if the heater blower motor stops working on a Sierra is it likely to be the motor itself or just the switch? I seem to remember reading somewhere that if the blower stopped working it was more than likely the blower motor seizing up through inactivity...or did I imagine that?
I'm having trouble getting a switch at local breakers so if I do find a car should I go for the blower motor as well??
Anyone had this fault and can remember what it was?

Cheers

Mike
