I have a request for some advice. I have an 87 300E whose rear windows will
not go down. when you press the switch you can hear something try to happen
within the door, but of course, nothing happens. I'd like to fix this
myself, as a local mechanic told me that it would probably be about $150 per
door to fix. can someone give me some advice on removing the door panels,
and what the problem might be? please reply to the newsgroup.
Thanks in Advance.
Most likely, the teeth on the window regulator are worn out and the regulator
needs replacement. If the $150 includes the part I would definetely have the
mechanic do it, if the part is not included (get used of course) do it yourself.
Also, the little plastic piece connecting the window control arm to the bottom
of the window could be broken.
Sixteen years ago, MB assembled your car with grease in the window
regulators that was the technology of the day. Almost every 1987 124 has the
same problem in 2003. The fix is cheap. Remove the door panel, the pvc film,
and lubricate the channels that the plastic "foot" travels within with ATF
(automatic transmission fluid), and your windows will glide up and down as
they should. Most MB dealers automatically tell customers that they need new
regulators ($98 each). P.
