I've lost power to the windows in my '01 F-350. I've got power at the breaker, the breaker shows continuity but I don't have power at the switch. It was working when I dropped it to a shop to have the oil pan replaced, they used the method of cutting the crossmember, didn't lift the cab. The last thing I did when I parked the truck there yesterday was raise the window up. Is there a likely spot I should look before crawling around under the dash trying to trace it?
