I have 1997 Mercedes E420. I bought the car with front windows not working. Replaced the bad fuse under the rear seat and also replaced the window switch that is in the center console. After all this my passenger window is still not working. I am able to roll the window up and down my giving it the impulse using one of my tools but not via the window switch (it only sends a short impulse to the door). Is there a window module or a relay that I need to check? Any help will be greatly appreciated.
