Hello. I own a 1999 W210 Wagon (WDBJH65F4XA748959).

The recent rainy spell in SoCal made me aware that the rear wiper & rear defrost have ceased to function. Upon further investigation there is also no power to the 12V socket in the third row seating area.

All the lights back there work. The wiper motor runs if I hook up a 12V supply. I can't find an obviously blown fuse but I'm not sure which one to zone in on.

Any tips gratefully received!

i don't own a wagon but here are some fuse charts for your viewing here

Thanks for the reply. Despite having north of 200k on the ticker the car is all present and correct including the little cardboard inserts with the fuse diagrams. Hence I've already snooped around the fuse box, I really thought one of fuses 12, 41, 44 (19) or 11 would be the ticket. But no, they're all fine. Plus systems that share fuses in common with the things that are out such as the rear reading light and tailgate assist still work. The fact that all three systems have gone out together seems to suggest a common fuse that serves a whole system. Or a common power line?

you mentioned 'fuse box' singular. so i hope that meant you inspected them all as you have
extra block say, in the rear wheel well. also, don't rely on visual inspection but to perform a
continuity test on the fuses. see if any of these attachments help
