BMW E87 power window faults and initialisation
E87 power window won't go up or down automatically – how do I initialise the window?
1. Close the window completely without the auto function by holding the button down. 2. Open the window completely. 3. Close it with the auto function and hold the button down until the window is up. In the end the window should work automatically up and down and drop a couple of centimetres when the door is opened.
E87 power window relay clicks, but the window does not move. What is the fault?
The fault is often in the wiring harness that runs inside the accordion rubber boot between the door and the A-pillar. Before replacing parts, it is worth resetting the window lifters' anti-pinch fault, because it can prevent movement.
E87 passenger window doesn't work and the window symbol with an exclamation mark is lit on the dashboard. What helps?
The cause can be the electric motor's brushes, which have stuck. Tapping the motor with a hammer frees the brushes, and the window starts to work. A longer-lasting repair is replacing the motor or the regulator.
