My wiper module went nuts and then stopped working 3 weeks ago. New module was put in. 2 weeks later I get in the truck and the wipers turn on with ignition. Can't turn them off. Drive home park truck because it's late and the weekend I can't get the truck to the shop for a few days. 3 days later I can't start the truck because the batteries are drained. Jump truck and it's running fine and the wipers are working normally. Drive to dealership service department and explain issue. 2 days later they can't find the issue. Wipers working normal but the radio and control power is on when the truck is off and keys out...that's what drained the battery but I didn't notice that when I parked it that night.

Any ideas? Or has anyone heard of this before? I need my truck back and reliable again.

Thanks,

Mark
