The BMW M4 has been marketed since 2014. It appeals to drivers with high-quality window switch parts. The BMW M4 window switch operates when the ignition switch is placed in the "run" or "accessory" position. But a faulty window switch can cause the windows to not roll up or down. And all of them stop working, or only one works.
The BMW M4 functions quite well in the beginning. However, the old window switch parts might lead to poor functions and unpleasant driving experiences after years of usage. They can be replaced as follows. First, disconnect the negative battery terminal. Next, locate the window switches. Third, remove the plastic trim panel. Then disconnect the window switch connector. Finally, remove the window switches from their mounting location. Symptoms of bad BMW M4 window switches include only certain windows that open, the windows that won't open, the windows that won't close, and the window motor that clicks but the switch does not activate the complete current.
