strange fault

chrisbrad66 · 19-11-2008, 11:51 AM

Hello all, this morning i replaced my front door speakers on my 2001 w220 i didn't remove the door cards just the speaker covers and the seat and mirror adj units, i did not undo any loom connectors or anything like that just pulled the whole unit to one side, i then replaced the speakers and fastened it all back together, then tested everything, now this is where it gets confusing so stay with me

1. The drivers seat adj and memory does not work
2. The passenger mirror will not adj but the drivers will
3. The passenger mirror will not fold but the drivers will
4. I can only open and close the drivers window and no other from the drivers door controls.
5. The interior light does not come on with any door open
6. The boot release button will not work
7. The drivers soft door close feature doesn't work

i have checked every fuse box i know of , all seems ok
i have removed the door cards again to check all connectors are sound all look ok, is there some thing i have missed or some unit i do not know of which will cause these probs, as i say i did not remove any electrical connectors at all just lifted it all to one side. i'm stumped!!!!
HELP

Did you disconnect the battery? Just out of interest

no i didn't but i did have to jump start it later as i spent ages with the electrics on trying to find out what i had done wrong, but this was after all the faults had appeared

just been on google and looked at the fuse locations for the w220 s class, seems fuse 13 is the only electric part that links all the faulty systems i have, next question is where is fuse 13?

sorted it, when i removed the seat adj unit to check the connectors it momentarily worked, i removed all the wiring connectors at the unit and checked all the pins for soundness, sprayed it all with contact cleaner and refitted the plugs, everything works as it should, job done.

Hi I notice you got access to the front door w220 speakers without removing the door card. I'm about to investigate a speaker fault but I can't see how to access the speaker just by removing the cover. I was about to take off the door card. How did you do it, please?

I'm still mystified. I have now managed to take off the speaker cover. As well as the bottom screws and side clips on the cover, a small alan screw holds it at the top. This is situated inaccessibly under the cover located above the speaker cover. I have also managed to prize out the speaker from its box. Do I also have to remove the cover located above the speaker cover? If so, how?
