Currently working on my lil 96 c280. The problem I'm having now is the driver window. Will not move up or down. All other windows and sunroof work fine. Have purchaced a Supposedly mb service manual cd online. And says the relay is behind the driver door panel. Not there. Have no blown fuses, removed the wires from the motor and both(2) have 10volts to chassie ground but nothing together. Have found relays under the fuse box bolt down cover just don't know what they are for. Any suggestions please.
Thanks all and have a happy Thanksgiving.

 

It be the day aftert christmas now. Have pulled said window motor and hooked straight to a battery. Yes the motor is good it runs forward and back. So now looking for the relay.
Thanks for all the help.

 

Found It. That bugger is located behind the battery in the trunk! In removing the cover can operate all windows manually. Sooo all this == good window motor good relays and bad switch. Will pull that puppy apart soon and see if just goop or bad contact can be fixed. Happy new year to all.
