What is the reason why the BMW 6 Series GT window cannot be raised?
2 Answers
BMW 6 Series GT window cannot be raised due to aging and deformation of the glass rubber seal; the window lifting guide rail is too dirty or has foreign objects; below are the reasons and solutions for the BMW 6 Series GT window not being able to be raised: Motor and circuit failure: Low battery power; motor failure; window regulator failure; mismatched glass rubber seal; window lifting function is turned off. Aging rubber and foreign objects in the window glass: If the window glass can be lowered but not raised, or gets stuck at a certain position during the raising process, it is likely due to aging rubber in the window glass and the presence of foreign objects. In this case, the window glass rubber needs to be replaced, and the foreign objects need to be cleaned out. Method for raising and lowering the window: Hold the switch, release the button when the window is lowered to the desired position; lift the switch, release the button when the window is raised to the desired position.
Last time I was driving my BMW 6 Series GT to pick up a friend when I suddenly noticed the rear window wouldn't go up. I got so anxious that I went straight to the repair shop. The mechanic said this is most commonly caused by a faulty window regulator motor, especially in older cars that have been driven for seven or eight years. It could also be due to foreign objects stuck in the track, like coins falling in or aging rubber seals deforming. Rainy days make it even more troublesome, requiring temporary sealing with tape. The most frustrating part is that this can happen right after replacing the battery, requiring a window initialization reset. I recommend against forcing it manually—it's best to visit a professional shop to read the fault codes with a diagnostic computer. After all, BMW's window system comes with anti-pinch protection, and improper repairs might trigger the safety mechanism.
