electric windows on '89 300se

[Oliverp]

Hi,

The electric windows on my drivers side seem to have died. Both the front and rear windows don't work. But it's a little more strange than it sounds though. The motors work, the windows go down. While they are going down the windows seem to clunk against something and the drivers side gets smeared with lubricant.
The rear window will not go back up and has to be pulled up manually. The drivers window goes up, but seems to go up at an angle and then jam.

Please help!!!

I think the car had a bump with the previous owner on the drivers side, because of the windows, and I think the side has been sprayed.

Thanks everyone

Oliver
