Electrical Problems Windows & Sunroof
 

Hello,

1994 E320 coupe

My windows and sunroof work most of the time and then suddenly they just stop. Slam the door, drive down the road a bit, go on in a store come back and then they work, and then they stop...It's totally hap-hazard.

Any ideas? Relay vs Short vs ???

Of note: Even when the switches won't work the key in the door still opens and closes everything.

I've fixed a few electrical gremlins and vacuum problems on him, this is just one more.

Thank you for the help...

hello, try the simplest things first the fuses are the ceramic ones (blue, red, white ) which over time in use the metallic stip (fuse ) gets cracks in it due to heating up and cooling down check the fuses first in fact best to replace as maintenance i've seen when cracks cause a interruption in power due to driving ,opening a door or just getting hot. and check all the fuse boxes in the car sometimes the description on the fuse car not always indicates other circuits that may be affected
