Windshield wipers not working. Won - 1997 Ford Expedition

hi David.
this is all i could find out.
The fuse is the safety device that breaks the electric circuit if it exceeds the safe level. If your fuse blows then there will be no way to stop the electricity from reaching the windshield wipers. This will cause your wipers to constantly keep going. ... You can easily tighten it and the wiper problem should be resolved.26 Feb 2013

Sometimes disconnecting the battery does more damage then you want it might have trip a fuse or relay check those if thats not it, maybe wiper motor or transmission went out.

Hi,
The 'stalk' that controls all these functions is faulty. Your truck SHOULD still be under warranty...Take it in.

Make sure wiper arms are tight they are on a spline also where the wiper arm transmissin conects to the wiper motor therw is a nut that holds a z shaped bracket that losens up and oblongs the rectangular slot so the wipers stop with the least resistance.

Check the relay relay maybe latched on. See if there is an identical relay in the box and swap them if problem goes away replace relay.

The WS wipers in this truck are controlled by a central module that is called the GEM, this module can be scanned to find the fault wirththe wipers, it could be the GEM that is defective or the wiper motor is defective. It also controls the WS washers do they work?

Sounds like the windshield wiper motor needs to be replaced. The gear inside may be stripped so you'll hear it running but it won't do anything. I've had that happen with the rear wiper motor. Hope that helps.
