So my blower fan fades in power after 15 min or so of operation on high. If I turn it off for a min and back on it works again on full blast but only for a min then tapers back off again. What does everyone think? Motor or the switch? The actually motor is pretty hot to the touch I might add but that could be normal I'm not sure.

My guess, high resistance in the motor cause by any number or ways. Motor heats up and resistance gets higher and motor gets slower. They shouldn't get very hot when operating but warm isn't out of the question. I'd be getting that motor replaced ASAP before it starts melting other s***... more current through the wires makes wires hotter and the trail keeps going. Don't burn the truck down lol.
