The front windows in my 1999 E300 quit working. Also the front power seats and mirrors quit at the same time. There is no fuse common to all these items so I think perhaps a ground wire has broken.
I need to find out if there is a common ground circuit for these items or could it be something else? Fuse #3 is common to the front two windows as well as the back windows but they work fine.

 

HI ck the fuse for the door control module

 

I have a 1999 C230 Kompressor, same problem, did you find out what the problem was?

 

I have not yet found the problem. The other day everything started working again. Today everything is dead again. I noticed that the FOB will not lower any of the windows or sunroof even though the back windows work as well as the sunroof from the switches inside the car. This leads me to believe that the problem is in the module in the drivers door. I can’t find a fuse that says it is for the any of the controllers.

This car is going to be a large pain in the rear if more things fail.

 

The problem goes away for a while if I disconnect the battery for a short while. A few days later the problem returns.

 

Just a thought... My passenger front door was having an issue going up and down. Sometimes if you cloesed the door like a guy it would work, but my wife never shut it hard enough to get it to work. Today I did some maint on the car and noticed on the door that there are 2 hinges and then a center hinge. The center hinge was very loose. No other doors were like this so I tightened it up and now the window works fine.... I wonder if that center hinge works like a ground?

Thanks, mine are all working fine now. I had my better half spend some time with it. But I have no doubt that there is something loose/short/or sensitive.
