Hi I drive a 1990 240. I am currently having problems with my power windows and decided to check other users info.

The heat and A/C don't work too well either. Temp is high all the time unless temp switch is in cold position. I've learned to live with it.

What kind of problems are you having with the windows?

My experience with the power windows is the switch gets gummed up or corroded.

Just use a small screw driver to pry the switch out of the door arm rest. Take the switch apart ( be carefull because the little "ears" are fragile) and clean the contacts. Careful not to loose the little balls.

Hi. They do not operate at all. Just happened suddenly. No warnings. Replaced fuse but that was not issue.

Thanks

I can't remember but on the 740 if the A/C compressor goes bad it blows the fuse and the windows are on the same fuse.Do they all not work from the master switch or not at all?
See if the fuse for the windows has power.
