What could be the caause of my heater motor stops working and then starts again? One day I went to start my truck and the heater motor wasn't running, so I turned the on/off switch on all the settings but nothing happened, then the next day I went out to the truck and turned on the ignition switch and the heater motor went on, now I went out there again today and the heater motor won't go on again. Is this the on/off/hi/lo switch going bad or is there something else that I should be looking at?
