[Ziggys Vegas]

Need help diagnosing wiper problem.

The windshield wipers and washers suddenly quit working on my new Vegas and I don't want to have to drive 100 miles to the dealer. The 30 amp fuse in the fusebox beside the radiator for the wipers is ok. I read somewhere that there should be a smaller fuse someplace that protects the wiper module. Does anybody know where the wiper module is, or is it part of the engine management module. Normally Ford puts the wiper module, and/or the engine module on the inside of he firewall near the steering column, and there is such a device on the Vegas, but I cannot see any other fuses or a separate wiper module.

There is also a 20 amp automatic reset fuse marked as "wiper" in the Battery Control Center that houses the "RV Custom Products" fuse panel for the house batteries. Question - are the house batteries somehow involved with wiper operation, or is the wiper switch installed by Thor not part of the Ford striped chassis and therefore somehow controlled by the Battery Control Center. The automatic fuse checked OK, but there was no voltage at either fuse terminal on the circuit board.

As far as I can see, everything else that the Battery Control Center should control is working OK, unless there is some electrical interlock that I am unaware of.
