The interior lights on my 94 C280 are not being switched on by the door opening switches. The front right passenger door will activate the front interior light, but the driver door will not.

The left rear door will not operate the rear interior light, but the right rear door will operat it.

Both front and rear interior lights operate via the switches in the overhead console and the switches are set for door operation of the lights.

Is there any common ellement between the front and rear left side door, or am I just lucky?

Any where I can get a wiring diagram?

Search function has been no help.

Thanks,
Gene

Without breaking out my own wiring schematic, I'd say you're "lucky". Can you remove and test the switches?
If someone were to ask nicely I could get out my ETM I suppose........
