My 8410 T's heater fan quit last fall and did not make any noises prior to just not working at all. I looked for a fuse but did not find any blown ones. Before I change the blower motor is there any resistor or something that it could be and should try first? It does not have climate control I have changed the blower motors in a 8000 before and I really didn't like the job so thought I should check other problems first.
