Electrical pointer please: window switch

1978 300SD, driver's side (US) rear window. Worked fine since getting the car a few weeks back, has been up/down many times in the past week of daily driving. Got in after work last night, dropped the window from the center console switch, drove home.

Parked, went inside for a bit, back out, window won't go up. Center console and rear door switches click as per normal, but nothing at the window - no motor noise, no "tries to go but can't" action. Driver's side front window operates fine.

Quick visual of the fuse box (driver's side, under hood) - all fuses look intact (haven't put a meter to them yet).

FWIW, tach and dash lights have been inoperative since we got the car.

Anybody happen to know which fuse would affect driver side rear window? Other fuse locations? Any other likely culprits?

Do both REAR windows work?

The Right front & Left Rear are on the same fuse

The Left Front & Right rear are also on their own fuse as well.

The center console switch for the right windows is in pieces in the center console tray .

Right rear doesn't work from the door switch, and hasn't since we brought the car home. Left rear DID work from the center console switch up until yesterday.

Definetly pull the fuses out when you inspect them. I've seen the fuse holders cut little circles out of the metal tips of the fuses. You can see it until you pull the fuse.

Also pull the switch and make sure its all clean, and you can also give 12v to the motor directly to see if it makes any noise. The motor has two prongs for the plug. Hook the + and - up one way the window goes up, and reverse the wires and it goes down.

Problem solved - was in fact a fuse. Looked fine from above, obviously split when I pulled it.

Thanks for the inputs everyone!
