Hi,
I am new to this forum as well as new owner of used 1997 E420. I got this car with front window’s not working. I started process of elimination and discovered that the fuse was blown under the rear seat and got my driver window to work by replacing blown fuse. I checked the fuse box on the right side of the cockpit and also one in the engine compartment and they are all good but I still can’t get the passenger window to work or the function to roll down all the windows up or down using the remote. My one touch is not working on the driver’s side as well and I did try to reprogram it. I can roll the passenger window up and down giving it the power inside the door panel which tells me that it is not my motor or window regulator. Is there a relay or some kind of module that I don’t know about that controls the windows? Any help will be greatly appreciated! Forgot to mention that the window switch is brand new as well and tested working.
Ok. I checked the control module and I can hear it click everytime you press the window switch. Is there anything else between control module and door that I need to check (relay,etc..)?
