My 300SD 1985 is having some problem with the electrics.
1. When I open the rear door partially, the inside rear light comes on, but as soon as the door is opened wider this light goes off and the right rear reading light comes on.
2. The light near the inside rearview mirror only works with the switch and will not shut off when the front doors are closed.
3. The light in the bottom of the front passenger door remains on when the door is closed, and goes off when the door is opened. This light remains on even when the ignition is off.
Any help or advice will be most welcome.
