Interior Lights major headache
I have a problem with my 86 300e
Three doors have a problem the light on the bottom won’t come on when doors are opened and the Courtesy light and Reading light in the rear wont work also
Doors Courtesy light trial
One door does work the passenger front doors lights up
So this morning I went and bought new bulbs and nothing three doors still no lights
Then I decided to try something I removed the plastic cover of the one that was working from the passenger door in the front and tested it on all the doors with the new bulb nothing still no lights at the doors
So I put it back in the front door and now that does not work also I was very careful as to not pull hard when I removed it but now nothing no power their also so four doors now with no Courtesy lights
Courtesy light and reading lamp in rear trial
Courtesy light and reading lamp in rear would not light up at all so I decided to check if it had power
And it did there are two metal bars one long and the other short and then you insert the bulb in between if I put the testing pen to the long one I would get power, and to the small I would not, I added a bulb but no light any way it wont light up
After my door trial and issue with killing the only door that had a courtesy light working (don’t know how it could have happened
Now the Courtesy light and reading lamp in the rear doesn’t have power at all also
I still have the front map light, which comes on when I open the doors but no courtesy light on any door or in rear for reading what happen?
All the fuses in the front box are ok no blowouts?
I also want to take this opportunity to thank everyone for past help I have saved lots of money here

Have you checked the pin switches at the each door hinge? You can compress them and pull them out to check them. Basically you need a schematic to trace the wiring back to the power source at each connection.
