W124 fog/side marker lights
 

My W124's low beams, high beams, and parking lights work just fine. However, the front/rear fogs and side marker lights (turning the knob to the left or pulling it out) don't work. I checked and the fuses are all fine. Any idea what this might be?

Thanks,

Grayson

Left/right parking lights only work with the key off, fogs only work with the lights on.

you only have 1 rear fog/extra road marker light. Turning the knob left only turns on 1 light front and rear each side at a time. Front fogs only work with headlights on. Just remember if the bulb dont work the bulb out indicator would show on the dash. And if the lights are not working and the bulb out isnt on your relay is shot.

Yes, I've tried all combinations--no lights anywhere. I guess my relay needs replacement then. :(

Try resoldering or throwing her in the oven first before an expensive replacement.
