Hi, I have a 2002 Quad Cab Sport with the 5.9 engine. I recently bought this truck and I'm waiting for a manual to come so I can learn more about the truck. I just noticed that the windshield wipers are not working. The fuse is good. There is also a place in the fuse box that says wiper high-low relay which has nothing plugged into it. I'm wondering if that is the problem. Also, someone had a DVD player plugged in under the dash and I'm wondering if something they did messed up the wiper switch? If you have any ideas about how I can track this problem down and fix it, I'd be very appreciative.
