86 300 SDL power seat wiring
 

Both seats quit working in the last couple of days. I checked the fuses and both are OK. Further checked the power and the problem seems to be no power to the fuse. If I jump to the fuse, then the seats will work.
Unfortunately, in the last move, I misplaced my wiring diagrams.

Has anyone got the wiring diagram for the prior to fuse block? If not, anyone have any suggestions?

Thanks !!

OK, making a little headway. Found the data disc now all I need is the Mitchell installation software.....ARRRRGGGG.....

The wiring diagrams are online as part of the factory manual for W126.

startekinfo.com, select workshop resources on the left, page through for chassis 126 manuals.

If that doesn't work, the seats for an 86 126 ought to be similar to a 124. There is a nice copy of the 124 wiring diagram (cleaner than the official MB one) at w124-zone.com You'll have to sign up but it's free.

From what I heard, they had a fire in their archives and the master copies of all the service data for the older models was destroyed. They had to find a paper copy of the books and scan them in.
