96 Bounder/Ford Chassis Wiper Problem Phil Grudzinski 7-27-02  
I'm still having wiper problems and I'll value any responses. RV dealership solution was to replace the Fleetwood wiper motor; didn't solve problem. Then they said it was a ground problem; cleaned up battery terminals and added ground wire to wiper motor. Just rained yesterday, and the wipers are still erratic. What happens is they travel across the windshield and stop in various places, about a minute later, return to stored position. Sometimes, it appears to happen more slowly when under acceleration (but this is not a vacuum system). All of this happens at any wiper switch position, i.e., low, high, or intermittent.

The wiper switch is Ford (F53) and part of the turn signal switch cluster. I'm thinking two or three possibilities. Since it occurs at times while under acceleration, perhaps low voltage to the wiper motor causing it to temporarily shut down? Or, a defective wiper switch causing the intermittent function to activate regardless of the switch position. I suppose it could be a loose connection or intermittent short somewhere, but I haven't been able to isolate it by jiggling the wiring/switch (where it's accessible, plus, the wipers generally work while parked with the engine running and stopped).

The dealer works on the Fleetwood items, but won't touch the Ford chassis parts, go figure! I will treasure any thoughts on this most annoying problem.

Check your wiper transmission arms. They connect to the wiper motor and work your wipers back and forth. The pivot points may need lubrication or may be contacting something that prevents the arms from functioning as they should.

Phil, It sounds like it is in the delay section of the switch. Even when the wipers are on low and high, power is routed through the delay. Some motorhomes have a isolated delay section. I'm not sure about yours. Also you may want to start at the wiper motor and trace the wires back checking for a brittle or broken section.

Thanks L, that's the first thing I did and forgot to mention in my post. I actually took everything apart and greased. Has to be electrical, I think.
