  7. Torque the steering wheel bolt to specification.

  9. 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 need to read BMW fault codes, to make sure that the problem is not the SZL module.

If your BMW wipers still don't work, there is a good chance that the wiper switch itself is the culprit.

Step 5 "Once the bolts are removed you can pull out the wiper switch and unplug it." There is a ribbon connecting the switch unit to the SLZ unit. How do I disconnect this? Cheers
