Afternoon All,

Just spent the last hour looking to see if there is a post on this but can't find one. The seats and mirrors in my 1999 R129 SL500 only work when the door is open, the radio has no life in it, all were working a few weeks ago. This all happened 2 days after it passed its mot. I've changed the fuse and no change. Does anyone have any ideas or gone through this?

By the way the roof and roll bar operate fine.

All the best

Gary

Hi,
Well no one has any ideas yet on this, so I will start the ball rolling with suggesting that you check all the Earth connections to the body. You might need a multimeter and check the voltages of the various components affected and wiggle wires until you can find some power getting through. If the MOT was a catalyst in the problem then think what they might have done out of the ordinary. Perhaps even something simple like moving the seat back or forwards may have damaged an earth connection somewhere.

Check the wires that pass through the door pillar .You will see a rubber concertina in the door that the wires go through wire or wires in there are probably broken.
