WINDOW WILL NOT COME UP

I own a 1989 300sel. Both back windows will not come up. I think the plastic clips have broken. The window motors still work fine. My problem is that I can't get the door panels off. What's the secret? :(

I've got an '89 300E, same problem but fixed if only temporarily.

The doorpanels are screwed in only a few places, the trick is finding all the screws and knowing which direction to pull to get it out, as it is also clipped in.

I had to detach the interrior handle at its base, which was fairly difficult, as the top is bolted in in such a way that you can't get to it until you have the panel off. There is also a screw at the rear portion of the door where it latches into the frame. It doesn't look like it is holding the panel in, but it is.

Once you get the panel off, it is likely that the cablehas become disattached from the window mount. It takes a bit of finnagling, but if you loop the cable over the upper pulley, you can coil the spring tight enough to clip it back into place.

No parts were needed to fix either of my windows.

Hello,
This was an old post however if by chance your driving around with a stick in the window to hold it. Don't pull the door panel off!
I would be willing to bet if the remaining three windows work the swicth group failed. THe part is relitively cheap and easy to replace. If your unclear how to do this go to the dealer and offer to give a tech cash as he is leaving for lunch. He can do it in 15 minutes and not break a thing.

Hope that helps

The cable-pull design is most likely at fault, as it can slip off the top pulley making it refuse to go up. If you hear *any* motor-noise (try when your engine is off) when you press the buttons, then the motors have power and it is likely a cable (mechanical) issue. If there is no noise at all, then it might be electrical.

I beg to differ with the last posting. Model year 2000 ML still had the old style window switch group.
I'm not saying the window regulator isn't bad however the switch group was a concern in those years (98, 99, 00) There is even a bulletin on this. (Net message 315)

Hope this helps

Its not the windows that broke, I have fixed alot of ML320's with the defective switch. The problem is that they are made in mexico and the window switch that are used frequently tend to break down very fast. The 4 window switches are also in one panel, so you have to replace all of them when you have this problem. Simply remove the glove box, gear cover, wood panel, and then you should be able to access the window switches.

Like the original poster, I also needed to remove the door panel from an ML. It is an easy task. If you need help take a look at these step by step instructions: http://www.mercedesmedic.com/front-door-panel-removal-ml320-ml430-1998-2005-w163-mercedes-benz/
