Electrical Short

[Dick Noble]

I have an '07 Dually, 3500. I just spent two days trying to trace down an electrical short. Both passinger side power windows and both power seats would not work. Took the seats out - no joy. Took the door panels off - no joy. Finally traced wiring from the under-hood fuse block through the firewall to a relay under the dash on the driver side near the steering wheel. Replaced the relay and no short. Reinstalled the cover over the relay and a wire went "ZAP". There it was. Cover had worn a very small hole in power supply to the relay. Boy, shorts can be hard to find! I had to google to find the 50amp fuse that controlled all those functions. Owners manual was no help.
