Hello! I had my 1990 244DL inspected in Maryland and one of the reasons it failed was that the rear fog lights are not working (surprised that I need them to pass inspection!). I turn on the headlights without high beams and the fog light switch and neither fog light comes on. All other rear lights work properly on both sides. I replaced the right tail light assembly a few days because a couple of the lenses were cracked - neither fog light was working before or after I replaced the assembly.

The bulbs are new. The fuse is good. The bulb for the fog light switch is not working either. I unplugged the fog light switch and tested the contacts with an electrical meter and it is getting current there. I cleaned the contacts. I tested that there was current at the fuse. I checked for current at the plug that connects to the circuit board and it is not getting current there. There are 2 wires that go into the switch - one is white and one is white with a blue stripe. I am correct to assume that the white wire that connects to the plug at the circuit board in the rear is the correct wire, right?

Any suggestions of what to do next?

Thanks!
