My cab fan is not working for either ac or heat.

I have looked at the fuses however there are 3 big silver looking fuses. Do either of these work the cab's fan? I have a 1994 Class C Minnie Winnie 24 footer. Does anyone have the correct placing of which fuses mean what for each fuse? My owners manuel does not give the layout for my model. Also it is a F350 chassis if that make any difference.

Dash air fan?

Not work at all or only work on high?

Correct the dash fan. Does not work at all. It was working a week ago but not now.

Sport, I lost the ground on the fan motor of
my last MH. As the duct work was of a fiberous
compsoition, and the one gr.wire got a little
krust on it and would not carry the amperage.
Took me the best part of a day to get to it,
so when I got there I change the fan motor.
MAYBE????? TENN.

As Tenn. says check your wiring and while your at it check both battery and ground with meter and see if you read the 12v's. Read the ground to frame ground with the ohm part of meter to see if you have ground.
