Cheers, I have a 87 300sdl, have the new part. Planning to to this weekend. But should check all relays too. When I trun the car off the engine stops but smoetimes the dash lights stay on ,, cycle the key on off a few times ends up tuning them off. Replacing the ignition switch is probably a good idea, but no garrentee that it is the root of the issue. Is there any relays that might be sticking on ? I do not have any diagrams of the circuts so any info would be appricated. Just did the low beams last week and it ended up being the big expensive relay,, after I had replaced the headlight switch :} ps sometimes when I close the door,, the lights go off also,,,
ty and cheers DD
