I posted about a week ago and received some good feedback, but the central locking system of my 1983 300SD TurboDiesel is still failing. When I turn the key on the drivers door, which should activate all the other doors, trunk, and fuel door, the drivers door opens but nothing else does. I checked fuse 13 which controls the central locking system and it's good. When I remove the fuse and then put it back, I can hear the pump in the truck activate, and it automatically locks any door that I manually had unlocked. The trunk is locked so I can't check on the pump. I was told that the switch on the drivers door carries power from a blue wire for lock, and a yellow wire for unlock. I'm not sure what to do next. I can't get the fuel door open and I'm running out of fuel!

Deja Vue all over again

I was in the same position once, but had the carpet removed from the trunk at the time and was able to reach through the back seat..... I think you should open up one of the doors and pressurize the system with one of those hand vacuum/pressure pumps to open the locks/fuel fill. My best guess is start on the rear passenger door. Good Luck

I would bet on the microswitch on the driver's lock assy has failed or one of the leads is shorted or open.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
