I've got a 95S420 and I am curious to find out how to get access to the mirrors proper also. My mirrors work, but I can't seem to get them to retract. When I move the console mounted switch to the retract position, both mirrors move a 1/4" rearward and stop. Is there a way to lube them? or is that all they are suppose to move? Your help appreciated.

Not sure how to take them apart, but they move/rotate about 85 degrees when retracted... they fold back against the door almost parallel to the door skin.

Thats what I thought should happen (mirrors almost fold flat). I'd like to try and spray some lubricant into the mirror to see if it will free it up. When the mirrors are closed against the car door, do you see any hinges or area's that they rotate about? Maybe you can give me some directions on where to aim the spray.

Thanks in advance

My 95 S420 needed (according to MB dealer) new mirror wiring harnesses on both sides. It was under starmark warr. still so they ordered the wire looms which tech says had insulation broken which was causing short circuits and keeping some of the movements from adjusting. Anyway, when they tried to do the work they realized they had ordered the wrong wires and the tech simply created the new wires and soldered in replacements of stock wire. Mind you I didn't really see any of this, because as you know they don't readily allow customer to watch-----but it now works correct and did'nt cost me so I stayed out of the way.
My fold function was also affected as was some of the movement directions. Its my guess that many of these cars have insulation breakdown, much as was widely reported on the engine harness. Perhaps folding movement (at cold temps) starts the trouble. I don't ever fold mine since I don't need to for parking and would never machine wash my car anyway. Some person my park in a tight city lot where they feel they have to fold, too bad. Also, if anyone tries to manually fold them they could be foulded up big time. Never allow manual fold. Luck fixing it. I do remember reading some posts about dissembly. Search , perhaps you will come onto those posts. A friendly, independent who would like to cultivate your future business might talk you thru the removal.

Sorry can't get to my car right now.... its all covered up and has a bunch of ice/snow on it... I don't use it in the winter.
Looked up the service procedures and it appears that the plastic cover simply snaps off with a pull; it separates along the seam that runs around the mirror. Procedure says to pull off the front piece first while holding the mirror firmly. ... but, I'd sure hate to try it if its cold... my experience is that plastic trim pieces don't take kindly to being pried on when they're cold... they break instead. Also, I think these plastic pieces are really expensive...
Proceed at your own risk!
Sorry not more help.
