Re: 4kq rear windows wont work/ switch is fine

Todd, I just went through the problems you are having on my 1991 200.  I
think what happens is that the rear windows do not get used, and the motor
corrodes inside and locks up - or at least that was my problem.  If you get
the switch off the door, there should be power to the switch, which can be
checked by using a test light.  If you have power to the switch (not the
light), then you can check the switch by holding it in one direction, and
then checking the two leads to the motor.  One of the leads should have
power.  Reverse the switch, and check the other lead to the motor.  If they
both have power when you press the switch each direction, then you have a
bad motor or cable.  New window regulators are on sale at Blau for $99, and
they are easy to put in, or at least they were on my car.  Good Luck!
