I've been tracing down a problem i have with both rear windows. (88 300e) They are stuck in the up position. I'm 99% sure it is bad motors. I have removed the left rear window lift. I have a couple of questions if anyone can answer. Is there suppose to a curvature to the lifting rail? The part of the cable which runs from the reel to the top pully is tighter than a piano string. On the other side of the pully(the down side)
the cable is very relaxed. Has the cable become so tight that it has pulled the lift rail from being straight. I assume that the lift rail should be curved because the window is curved. Just want to be sure. Also, what size hex tool is required to remove the two bolts on the motor from the reel housing? Any other helpful hints with regards to replacing these motors are appreciated.

I replaced mine. Unfortunately, the do not sell the motors separate for the rear windows (unlike the front windows). You have to buy the whole assembly which cost a little more than $100 new, unless you can find a used one. I tried to clean the assembly, oil, no go!. Have you try to close the door while holding the swicth down? If it goes down, your problem is most likely the motor. BIG difference with the new assembly, no problems since. If that is your problem, buy a new one and forget it for another 12 years.
Good luck!
P.S. Mine also had a "mild bow".

Thanks for the response. I'm probably going to buy the new regulator. It will most likely be easier to replace the regulator (with motor). Awaiting a price from the parts shop. Its really not that bad to replace the parts. I found it more difficult to remove the door lining.
