Side mirrors and defrost inoperative

[Willynojob]

2000 Class A Windsport motor home on F 350 chassis, both side mirrors and defrost are inoperative. The best I can tell it is not the fuses, had them checked at the repair shop. Any help out there, please?

This is not a Ford problem. These items were in stalled by the Coach maker and not Ford.
I would call Thor Motor Coach (the maker) and ask for a wiring diagram.
By the way you have a F53 chassis and not a F 350 chassis.

have they ever worked? I acquired a 98 windsport with a power mirror switch, electric defrost, etc. but the passenger side mirror is not even electric, no motors at all. I can't say about the drivers side as it was missing when I bought the coach

Yes, both the mirrors and defrost worked but not now?? On another blog (RV.Net) Mentioned faulty switch, I will check there first. Thanks everyone for input.

I had the same problem on our 96 southwind (ford chassis). It turned out to be a bad relay in the intellitec power/battery control box. It was the "ignition-aux" relay, the mirrors and defrost are the only things powered by it.
