For the sake of future W126 owners searching this forum...

1) remove the ash tray assy (gently pull it out of the console (below radio, towards shifter))
2) remove the coin/junk tray forward of shifter gently pop it upward
3) gently slide wod trim panel with window switch assys forward (toward front of auto)
4) driv and pax side switch assys can be gently popped out (upward) of/from trim panel after you disconnect the harnesses
5) window rocker switches can then be replaced or repaired.
6) to inspect/clean rocker switch contacts
a) gently pry the sides of switch adjacent to rocker switch pivot point and remove switch "cap", be careful to retain two spring points in the switch cap bottom.
b) use some tweezers to remove pair of rocker contacts below and clean any carbon/corrosion evident on contact points
c) reassemble switch
d) testing: plug switches into wiring harness and check windows for function (note - you can use working driv/pax side switches on pax/driv harnesses to check if problem is in switch or between console and door or window motor, also note contact pins in stitch and harness are different for front and rear)
7) reassemble trim panel with switches and plug in wiring harnesses, reverse the above removal steps.

Enjoy your restored 300SD/3000SDL window operation [:)]

Their are two small screws in the ashtray! Don't just pull it out!!! The tray inside with the chrome cigar holder pops out letting you remove the screws.

RE: W126/300SD/SDL console removal & window switch repair

Hattaresguy/All:

You are correct [:D] you can see/remove the two screws (or their holes) after you remove tray from the ashtray unit.

A previous owner of our '83 300SD removed the two screws you mentioned and did not reinstall them. The ashtray frame fits into the slot below the radio fairly snugly so you could possibly consider them optional on reinstall.

Another note on rocker switches repair, our '84 and I assume '84/newer have ball bearings (vice plastic pins as in our '83) at end of springs in rocker switch cap. Be careful you don't lose the ball bearings when dissessembling the switches to clean contact points. A pair of tweezers are handy for reassembly.

Clean the other switches: Another suggestion is to save yourself a future dissembly and clean all the contact points in all four of four window switches (as long as you have the center console trim out). Other dirty points will eventually cause another window to stop working.
