take the SJB loose and find wire from 30 amp supply and ck for power if ok it is probably an SJB issue, ck wiring diagrams and make sure you ck correct wire at SJB input. Also make sure the light switch input to SJB shows good. Don't have diagram in front of me, but I have seen this issue several times. Check to make sure you don't have water intrusion. Also if you have aftermarket lamps be sure they don't exceed the wattage recommended by Ford. Some of these modules need to be programmed when replaced, ck the manual for aplicable programming. |
