SL/R129: 500sl 1992 light problems
Really need your help,
Unfortunately every day I find a different fault in the car and the truth is that I got a little lost.
I noticed that I have a problem with the car's lighting,
The right parking light works and the left does not
Instrumental cluster lighting half works and half doesn't
Lighting in the driver's door neither works nor has any effect when opening the door.
I replaced all bulbs, they are fine.
My question is if all of this is somehow connected? Is there any central unit in the car that controls this matter?
