Are the wipers on your BMW not working? Following the steps below, learn how to replace the windshield wiper switch on a BMW.
Airbag safety: Before you unplug any airbag, clock spring or seat connector, switch the ignition off, disconnect the negative battery terminal and wait at least 10 minutes so the airbag system’s backup power drains. Never probe airbag connectors with a test light or meter, and set a removed airbag down with the padded side facing up, away from your body.

Remove the steering wheel.
Pull up the steering column trim.
Remove the wiper switch from the steering column switch unit. Two T20 Torx bolts hold the wiper switch in place. Once the bolts are removed, you can pull out the wiper switch and unplug it. Install a new BMW wiper switch in reverse order. Torque the steering wheel bolt to specification. Reinstall the driver’s airbag. Reconnect the negative battery terminal and check the operation of the windshield wiper switch.
Note that if you moved or rotated the clock spring, you may need to calibrate the steering angle sensor. Follow this guide to learn more about the BMW steering angle sensor and calibration procedure.
If the wipers on your BMW have stopped working, first, you need to check the fuse and the wiper motor. Next, you must read BMW fault codes to ensure the problem is not the SZL module. The wiper switch could be the issue if the BMW wipers still do not work.
