Removal
1. Wet the windshield with water.
2. Turn on the windshield wiper and let it run for a short time. Turn off the wiper. The wiper blade should return to its original position.
3. Remove the key from the ignition switch.
4. Mark the position of the wiper blade on the windshield, using, for example, tape. It is assumed that the position of the wiper arm is adjusted correctly and the marks applied will be the standard (see illustration).
5. Remove cap 1 and unscrew nut 2 by about two turns, but do not unscrew it completely (see illustration).
6. Move the glass wiper arm 3 to one side and then to the other to loosen it on the shaft. Then completely unscrew the nut, remove the washer and the arm from the shaft (see illustration 19.5).
Caution: If the lever is too tight on the shaft, place a wrench under the lever and carefully lift the lever.
Installation
7. Make sure the wiper motor is in the home position. If necessary, turn on the ignition, then turn on the wiper motor briefly and turn it off.
8. Install the wiper arm onto the shaft, using the marks made with tape before removing the wiper.
9. Place the spacer washer, screw on the lever mounting nut and tighten it by hand.
10. Check the initial position of the lever again. To do this, wet the windshield with water and turn on the wiper for a short time. The lever should return to its initial position, and the brush should not go beyond the edge of the windshield during operation.
Attention! When checking the operation of the brush, set it to the upper position, and only then turn on the wiper. This technique allows you to correctly determine the parking position of the brush.
