Windshield Wiper Arms, Adjusting

Procedure

NOTE:

If the windshield wiper motor is to be run during the work procedure, the hood must be closed. Otherwise, the voltage supply of the wiper motor will be interrupted.

-- Remove the windshield wiper arms. Refer to WINDSHIELD WIPER ARMS, REMOVING AND INSTALLING .

-- Turn on the ignition.

-- Activate "One-touch wiping" and let wiper motor run to end position.

NOTE:

Every second time the windshield wiper motor is switched off, it returns the wiper arms to a lower rest position, thus tipping the wiper blade lips the other way.

To do so, the windshield wiper motor moves the wiper arms farther down than to rest position and then a bit up again. This lower rest position must not be used to adjust the wiper crank.

Only use end position where wiper arms run directly into the end position with no understroke. Activate "One-touch wiping" again if necessary.

-- Turn off the ignition.

-- Position the wiper arm with wiper blade installed at the wiper axle.
