I came out to my '87 Toy Dolphin to find the windshield wipers going! Spooky! I pulled the fuse, and they kept going! I had to disconnect the connector at the wiper motor. (If they didn't stop then, I would have run away very fast.) My guess is that some 35 year old piece of plastic broke that was keeping the park switch open, and it closed, which will run the wipers continuously, and since that switch is fed directly from the battery, pulling the fuse won't help. Now to Rock Auto for a Cardone reconditioned unit.
