MY 2000 Series F350 has just started to do the following, It won't Start in park, and I have no brake lights (including the third brake light). I checked the fuses and bulbs, they all seem OK, If I put the car in park after turning the key out of lock The truck will start, but it still has no brake lights. I checked the brake light switch and it has continuity. I understand that this is a common problem but none of the car parts places have a clue? The ford dealership has an idea waiting at $95.00 per hour, two hour minimum service charge. does anybody have a cheaper answer? What could be keeping power from going to the Start/shiftlockout/brakelight circuit?
