Hello,

Car is '86 300E W124 176k miles. This morning I have lost power to all 4 windows and seats. It all worked yesterday -- at least all that I used. Where do I start? It really seems like a wiring harness or main hot or main ground has failed somewhere -- hoping someone knows where to look!

Fuses are all OK.

Does not work: in any key position
Seats
Steering Wheel
Windows
Added on 4/1:
Wipers and Wiper Wash
High Beams
Rear Defrost

Does work: with door open:
Seats

Does work: normally:
Radio
Antenna
Climate control
Cigar Lighter
All switch illumination (even to the window switches)
Headliner lights
Glovebox light

Thanks!
