Windshield Wiper Arms, Adjusting
Procedure
‹› 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 wiper arms. Refer to => [ Windshield Wiper Arms ] See: Service and Repair/Removal and Replacement.
-
Switch on ignition.
-
Activate one-touch wiping and let wiper motor run to end position.
‹› Every second time the wiper motor is switched off, it returns the wiper arms to a slightly lower rest position, thus tipping the wiper blade lips the
other way.
‹› To do so, the 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 end position with no understroke. Activate one-touch wiping again if necessary.
-
Turn off the ignition.
-
Position wiper arm with wiper blade installed at wiper axles and align wiper blade at windshield as follows:
‹› Dimension - a - = 10 mm
‹› Dimension - b - = 10 mm
