One problem related to dash wiring has been reported for the 2003 Ford F-250. The most recently reported issues are listed below.
After towing my trailer several blocks I pulled over at my destination and realized my trailer lights had gone out. This is unusual because the trailer just made a 2500 mile trip with no problems. After checking the connections and opening up the fuse box to look for blown fuses I went back to check the lights again. Upon returning to the truck several minutes later I found the fuse box and a portion of the dashboard in flames. I smothered the fire and found all the electronics to work with the exception of the passenger power seat and the trailer lights and brakes. The vehicle is a 2003 Ford superduty lariat F-250 5. 4l.
