300CD rear window issues

I just bought a 300CD. Got a good deal but the previous owner seriously neglected the interior. I stripped out the interior and cleaned it. Now I'm getting all the windows working. So, here's my question:

the rear windows don't want to slide smoothly in their track. I've lubricated them and attached the motors but just when I think everthing is working right and I want to put the panels back on, the window sticks, the motor keeps pushing and the pin holding the two together pops off. It seems that both windows are getting caught at the same place; the side closest to the door. I imagine this is a common problem. If anyone has done this before or can lead me to previous discussions of it I would appreciate it very much.

Also, when I do roll the rear windows down they stop about 3 or 4 inches before being completely down. I've seen photos of this car with the windows all the way down. I really like the postless look of the CD. Any comments on that?
Thanks
izick

Anyone with a 300CD

If you've had any problems with your windows or have access to photos of how the motors are connected to the window mechanism please reply. I can't figure these things out...

Windows do drop completely out of site. No problems on mine. Have CD-ROM's from MB, also having computer glitches. Someone send their grand kids to help me with them!

Your problem is that your lifters are bent.

One of those brackets was bent on my car. Straightened it out and now works fine. Later on I discovered by accident that Mercedes knew these were a problem and replacement brackets have a flat strip of steel welded between the two parts of the bracket to act as a strut.

You're right. They are bent. I bent them back as much as I could but they still get bound up if I roll the window up too fast. I guess the best thing to do would be to remove the bracket, straighten it and weld a brace on?

They get softer and bend even faster next time.
You could weld a support in there, but JB Weld won't hold.

New are around $90 each.

A friend has the same problem on his '79, he finally got to stay up, and doesn't touch 'em anymore.

If you have a small wire welder, or a friend with one, it would only take a few minutes to weld the strut on. Heck, a muffler shop probably would do it for you for a few bucks if you have the parts ready to weld. Just make sure they are bent correctly before welding. You can buy flat steel strap at any hardware or some home improvement stores. Wish I had done that before I reassembled mine, but so far mine have been working.

I took the brackets out and straightened them as best I could. Then welded some 90 degree brackets on each. The welds were ugly but they work. I put em in today and they work perfectly.
