The Audi S3 is derived from the A3. During its development, Audi has built many popular S3 window switches. But a faulty Audi window switch can cause the window to not roll up or down, all of them stop working, or only one works.
Whereas, the worn window switch parts need to be repaired or replaced for better S3 performance. The Audi S3 parts can be replaced as follows. Disconnect the negative battery terminal. Locate the window switch. Remove the plastic trim panel. Then disconnect the switch connector. And finally, remove the switch from its mounting location. Signs of bad Audi S3 window switch parts include only certain windows open, the window won't open, the window won't close, and the window motor clicks but the switch does not activate the complete current.
