Cari Alfisti,
I have quite a disturbing electrical gremlin with the interior lighting on a 1993 164.
When the car is in motion, the front upper central interior light comes on & off intermittently, and sometimes it flickers. The problem gets worse when going over bumps and potholes.
I realize this has to be something with a connection or faulty earthwire but after a whole day outside tampering with the electrics I havn't been able to solve the problem.
Here is what I already did:
1. Cleaned the fuse & relay box (the main one lower left side of panel), sprayed everything with contact spray and re-installed.
2. Loosened the lower flange under the box holding the connectors, disconnected all, cleaned and reconnected.
3. There's a control unit under the glove compartment responsible for the check controls and interior light delay - I noticed it is also responsible for the interior light delay when engine is running and doors are open. When I dismounted it, cleaned all connectors and played with the wiring it seemed to have solved the problem but alas, a short run and the problem persists.
The only thing I still suspect is that the door jamb switch is faulty, or otherwise it's wiring causes a circuit to remain open - BUT WHERE THE HE** ARE THE DOOR JAMB SWITCHES??? I havn't been able to figure that one out. This also puzzles me as I don't see any "DOOR AJAR" indication on the panel.
For now I removed the fuse so there's no front interior light at all.
Aiuuuutttoooooooooo!
Thanks for your responses.
