I have a 1997 Holiday Rambler, Vacationer. With a 460 Ford Chassis. The dash AC and fan have worked on and off since it was new. For some time I had the fan working properly until I stored it. Now it quit. I took the TV out and traced all the wires looking for a mice-chewed wire or loose connection. So far, no luck. There is no schematic that I can follow. Fuses and wires seem to be working and so is the fan, manually and directly wired to check it. May be some one had this problem and has the answer.
