[LaElle]

BMW 5 Series sunroof switch button not responding may be caused by faults in the sunroof-related devices or abnormal conditions of the sunroof guide rails. Faults in sunroof-related devices: First, check if the fuse of the electric sunroof is blown. If the fuse is intact, then inspect whether the electric sunroof switch is functioning properly. Press the switch to see if there is power. If there is, further check if the drive motor of the electric sunroof is working by listening for any operational sound from the motor. Abnormal conditions of the sunroof guide rails: The sunroof may be blocked by foreign objects, deformed, rusted, or suffering from poor lubrication. It is recommended to pay attention to regular maintenance and periodic cleaning.
