If the wires between the blower speed processor and the blower are getting hot, the blower may be pulling too many amps. The only way to validate it would be with an inductive amp clamp. It seems to me that anything over 25 amps after run-up is excessive. If you are into replacement, I would replace the blower and speed processor.
