2003 F350 Superduty electrical problems
I just bought a 2003 F350 Super Duty. It has several electrical problems that may be related but I can't figure it out. Here are the faulty items:
* tail lights
* parking lights
* instrument cluster lights
* windshield wipers (the motor unit clicks when engaged but doesn't move)
* windshield washer pump (pump works when connected to 12v)
* trip computer
* cruise control
Fuses #17 (lights) and #33 (wipers, etc) are good. The Smart Junction Box seems to be a common element but I don't know how to troubleshoot it.
Headlights, backup lights, door locks, windows, seats, etc all work.
