1991 Mercedes Benz 300d power windows

most of the time on Mercedes the Windows stop working due to spilling your drinks and food on the switches, you may have to remove the switches take them apart carefully and clean all the debris out of them. I am giving you a component location to the window relay make sure it is working let me know what you find. COMPONENT LOCATIONS Component Location Convenience Control Module (1) Location Under left side Of Rear Seat Convenience Control Relay (K24) Location Rear, Left Side Of Engine Compartment In Fuse Box Front Door Pin Switch Location Appropriate Door Jamb Fuse Block Location In Engine Compartment Power Window Switches Center Console & Appropriate Rear Door Rear Window Safety Switch Center Console (1)1990-95 vehicles are equipped with a 4-power window system.

I have checked the switches. I have ground going through the switch when it is pressed. I also jumped ground to the wires going from the switch to the convienence module under the rear seat and I cant make the windows move. When the switch is pushed and sends ground to the module there is no power and ground coming out to the window motor.

So the next step is to find out why there is no power, check the K24 relay under the hood make sure it is getting power.

Rear, Left Side Of Engine Compartment In Fuse Box

I do have power at the convienience module frome the k24 relay. so does that mean I have a bad module?
