I have a 91 Lincoln Town car and the wipers work when they feel like it. I have the best luck in high speed, but sometimes that doesn't even work. Also, if I leave the switch on they will eventually work for a while - maybe. I've tried the washer/wiper button, that gets them running periodically. Much of the the time when the wipers do work they will eventually slow down and stop. The wipers park just fine. It is getting them to run in the first place. Any ideas? I live and work in Seattle. It rains here once in a while.
