Yesterday I noticed my sunroof, windows, & seats stopped working,however the seats work when the doors are open. The fuses all seem good and I moved them around to make sure they were making good contact. Has anyone ever had this happen ? Is it a relay? Where can I find this relay or fuse? This happened once before I put the hazard switch on and everything worked again.The hazards are working,but not having the same curing result. Thanks for any help!The car is a 1991 300E 4-Matic.

what year and model do you have?

Sorry, the car is a 1991 300E 4-Matic.

check all fuses any way. i have seen them with fine cracks that are hard to see. check the one for the cigar lighter, not sure if this is what you have, but i have seen change from the ash tray fall into the cigar lighter and cause similar issues.

I checked the lighter/fuse and the ashtray has never been used for anything & looks brand new. Any idea where the relays are? I want to inspect & maybe give them a technical tap.

the only other thing is the resistor may be bad. it is 201-540-11-81, it is white, grey or maybe even black, it is under the fuse box area, i will get you a picture if you want, let me know
