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 ] Windshield Wiper Arms.

- 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 - = 15 + 5 mm.

• Dimension - b - = 45 + 5 mm.

- Switch on ignition.

- Operate one-touch wiping and let wiper arms run to end position.
