Have you ever tried to open the window in your BMW only to find that it is jammed? You’re not alone. The window regulator is a device found within the car door that is used to manage the movement of the window. When you press the window switch, the regulator which is motorized will then move the window up or down. A fault in the window regulator can cause the window not to open or close properly. Below is a guide on how to go about BMW window regulator repair.
Diagnosing the Problem
- Check Window Sound and Movement: As you prepare to repair the window regulator in your BMW, you need to first identify the problem. Begin with checking whether there are any strange sounds that can be heard when the switch of the window is pressed. Every grinding or clicking sound suggests that there is an issue with the regulator or the motor. It is vital to assess the window movement. If it is slow or becomes stuck at some point, then this is a sure sign that the regulator is faulty in some way.
- Inspect the Switch: At other times, the issue might be with the window switch and not the regulator as people tend to think. Push the switch and check to hear the motor running. If the motor is operating, but the window does not respond, then it may be the regulator. To see more of the regulator you will have to take off the door panel. This is done by unscrewing some parts and gently applying force to take the panel out. After removing the panel, one can efficiently examine the regulator, cables, and motor.
Fixing the Window Regulator
- Prepare For The Repair: After you’ve identified the problem, it’s now time to solve it. Ensure that you have all the right equipment for the repair before you begin. Switch off the battery to minimize the chances of electrical problems when fixing the window regulator. Take off the door panel to get to the regulator, but be very cautious not to snap any clips or wires.
- Remove Window and Old Regulator: When the door panel has been removed, the window has to be disconnected from the regulator, which is done by removing bolts or clips that secure the window in place. Once you have taken out the window, you can then take out the old regulator. This may require the further unscrewing of extra bolts and detachment of the motor.
- Install New Regulator: Replace the new window regulator after the removal process in reverse manner. Put the regulator to the door, fix the motor then fix the window. Before fixing the door panel back, one should open and close the window to ensure that it glides as it should. Push the switch to test whether the window can go up and down correctly.
- Reassemble: Once you are confident that the window regulator is back in the right order, then you can reinstall the door panel. Ensure that all the clips and screws are well-fitted. Lastly, connect the battery and try operating the window to confirm that all is well.
