Today,out of the blue,my '90 300E suddenly has no juice to move rear windows up or down. Any likely cause? Known fixes? As usual,any and all advice is wanted and appreciated!

Does that car have the lockout button? A square button between the front and rear switches? Maybe inadvertently changed.

No,there's no window lock button. However,the push buttons in the two rear door handles still work the up& down,so,for now,I just won't worry about the 2 switches on the console not working. As I can keep the rain out and can,once again,feel comfortable locking the car,I'm all set,for now. Thanks for the suggestion.
