92 Ford Grand Marq Wiper Problem

[Riger]

Hello All

I have a 1992 Ford Grand Marq, great shape and never any real problems until now.

A day or 2 ago the wipers had stopped working for no reason, checked fuse and it was fine, went to a garage thinking it was a wiper motor and was advised it was not but that it could be the "Switch" but I would have to go elsewhere because they were concerned with deploying the airbag and costing more money, the newest garage (2nd) has now said it's not the switch but they have no idea what it is and want to continue to trouble shoot further, which is fine unless I am being a fool but it really does need fixing.

Has ANYONE else come across this type of problem in the past (wipers stop working and fuse, wiper motor are fine) and what did the issue turn out to be? I am not really knoweledgable about cars but would this have a govener or some type in it perhaps getting in the way??

Input is very welcome!

Thanks, Rick
