E220 Passenger Window Issue
Dear Brains Trust,
I have a E220 and the passenger window wont wind down or up, whether triggered from its door or from the driver's side buttons.
There are no sounds coming from the window motor, however when I lift the window button to open the window, there is a faint click sound then stops. The window doesnt move eitehr way though.
I have opened the door cover and measured the DC voltage coming of the controller to the window motor ... zero! However, when I pull up on window lever, there is a very brief voltage which then disappears.
Am I correct in assuming that the controller is busted? Is it a matter of just buying another controller? Or could there be something else that I am missing?
Is it possible that just the window output of the controller isnt working, but everything else is ok?
Thanks in advance for your assistance.
Cheers,
Pete
