Talked to Marathon and they told me that there is no fuse to stop the front blower. Talked to Prevost, and their technician said the same thing. Took the bus into service to replace drive shaft seal and ended up talking to them about the blower. They pulled the wiring diagram and solved it in 1/2 hour. There is a circuit breaker (#79 in my bus) in the front bay that controls the blower motor. They reset the CB, and everything works perfect.
