Heater fan only works while vehicle is in motion.

Has anyone come across this problem before? I'd like to think its something simple. Haven't had time to look at yet but thought I'd ask here first. Thanks.

Could be that the bearing is going out on the fan, and the fan gets stuck on the box keeping it from moving. Then the vibration and movement of the truck while driving shakes it away from it's stuck position?

Either way, I would say pull it and inspect it and the box for junk.
