I have a F350 2002 Diesel 4x4. My problem 1st started with the automatic lights flashing on and off at the same time the door locks would lock. Then the automatic lights stopped working . The power door locks will not lock or unlock with the switch. The radio will not shut off on it's own when the key is turned off and the door opens. The inside light will not come on when door is open. If I disconnect the positive on the batteries and let sit for a few minutes then connect back up . Everything works again except the automatic lights. Then not long it is back to not working. Any idea's. Is it the computer going bad. I wanted to have a idea what could be the problem before taking it in to Ford and giving them car blanche. I have read on threads this same problem but never heard what the problem was and how it got fixed. Any ideas?
