I have tried that a million times. Still nothing. Any other sugestions would be greatly appreciated. I would love to roll my rear windows down.

I know someone out there in the MB has heard of this and has fixed it.....where r you , ole MB GURU....Where r u?

You probably already know this but to be sure...

The windows won't roll down with the second detent until you do the full up for a couple of seconds routine. You have to do this each time you restore power.

If that doesn't do it then maybe there's a problem with the convenience module. Might also be related to your battery drain problem.

Maybe your problem does lie with the electronics as the others have said. My 300E isn't so complex. However, I've found that the rear windows on my car often will not open after a long period of not opening them. It seems that the windows stick to the seals. I gently tap around the inside and outside edges of the windows using the heel of my hand. After doing this once or twice, the windows will open. I'd bet that this is why the PO kept having the window switches replaced unnecessarily. It helps to have the engine running so the higher voltage gives a little boost to the window motors.

It is a good idea to "exercise" each window at least once a week to prevent the sticking.
