Have an F-250 7.3 2002 w/Superchips. Automatic door locks starting acting funny then quit working. Now these other things have gone haywire: Door ajar light stays on, dome light works but does not come on when I open the door, radio used to shut off when I opened the door with the key out, headlights on and open door with key out and alert beep does not go off now, and this all might have started with headlights in automatic on position and I started hearing a clicking noise and then the dash lights would blink every so often.

I checked two fuses related to these items but they were okay. Checked DTC codes and had one: P0603 internal control module KAM error.

Appreciate your help!

 

I had simular problem with my 00' f250 5.4l. It turned out to be my gem computer (generic electronic module). I'm not saying thats your problem, but might help you out. A new one was 475.00. Had to have it checked out by a service tech.
