Last week, my electric seat started turning on themselves. I still haven't narrowed down the reason, but unplugged them for now underneath the seat. Now my windows will not come back up.

Are they connected electrically in any way. All fuses are relatively new...

Any help? Thanks

NO! seat heaters are controled by electronic relay. Windows on upto 1990 cars are hard wired, power & ground come from switch. Do you have W124 cd? It has wiring diagrams.
