3360309 - M03 ONE OF THE ELECTRIC FRONT WINDOWS IS NOT WORKING

When the appropriate switch is pressed, one of the front electric windows, left or right, does not work properly.

The window electrical motor is controlled directly by the relevant door node, which receives a window open/close command from a switch on the door panel. The door node supply is protected by a special fuse housed in the underfacia junction unit, and controlled by a relay which is also housed in the underfacia junction unit
