Background and Instructions:
You're driving along one day, minding your own business. You try to
roll down the window--probably the rear window--only to hear a
horrendous clunking, grinding, and snapping sound.
Hopefully your window is still suspended in its track, but it also might
have fallen into the door panel.
Chances are you just experienced the all-too-common window
regulator failure. Thanks to the bean counters,
M-B's vendors obviously cut a few corners in producing this fine car.
Luckily, this one is not too tough
to fix for anyone with decent mechanical ability (harder than an oil
change, but easier than a brake job). The regulator is just a fancy
name for the channel & pulley system that guide the window's path.

The motor is attached to the regulator, but is rarely the culprit with
W210 window problems.
The first thing you have to do is tape the window in the up position,
Now let's start the door panel removal by removing three simple
phillips-head screws. The first one is accessed by gently prying the
door handle liner away from the door. Set it aside

The second one is behind a round cap in the middle of the door. Set
the cap and screw aside.

The final one holds the door latch frame onto the panel. Set the frame
and screw aside.

Now it's time to work the panel loose from the metal door. Take your
pry tool or screwdriver and gently work around the outside of the
door. The attachment points are pretty obvious, since they are the
points where the panel is held on especially tightly.
Just work your tool in and either pry or twist slightly. You'll hear the
ribbed fasteners pop out easily. It's not uncommon to break a couple
of these along the way, but you can find cheap, better-than-OE
replacements at home improvement stores. When the panel comes
free, you'll see this:
