Sequence of works
Removal
1. Remove the wiper arm.
Fig. 3.16. Removing the protective air intake grilles
2. Remove the left and right air intake protective grilles by first removing trim 1 (Fig. 3.16) by unscrewing screw 2 and lifting the clamps (thick arrows). Remove the trim to the right and left (thick arrows right and left). Unscrew the three screws. After releasing the clamps (thin arrows: left - three, right - four), remove the grilles.
3. Remove the lever mechanism cover.

4. Disconnect the plug (arrow, Fig. 3.17) from the windshield wiper gear motor.
5. Unscrew the nut on the drive flange on the left and right and the screw on the gear motor.
6. Use a screwdriver to lift up the rubber ring clamps on the lever mechanism.
7. Remove the windshield wiper motor together with the lever mechanism.
8. Before dismantling the gear motor, clearly remember or draw the position of the wiper lever and the lever mechanism.

9. To disconnect the windscreen wiper gear motor 2 (Fig. 3.18) from the lever 3, remove the nut 1 of the drive crank and the three fastening screws (arrows). The gear motor crank and the extendable rod practically form one line in the middle position. When dismantling the lever mechanism, it is important to maintain the middle position of the wiper blade and the lever mechanism, which is fixed using the axial nut 4 of the drive head.
10. Remove the windshield wiper motor together with the lever mechanism.
Installation
1. Make sure the gear motor is in the middle position. If not, connect the plug, turn on the ignition, turn on the gear motor briefly and turn it off using the windshield wiper switch. Then turn off the ignition.
2. Tighten the gearmotor mount with a tightening torque of 5 Nm.
3. Place the lever mechanism on the gear motor crank.
4. Connect the wiper lever with the lever mechanism according to the drawing you made during removal, and screw the nut onto the gear motor shaft.
5. Place the crank arm on the gear motor shaft so that the crank arm and wiper arm form one line. Tighten the fastening nut with a tightening torque of 20 N·m.
6. Attach the wiper blade and connect the plug.
7. Install the rubber rings and tighten the screw.
8. Install the windshield wiper.
9. Place the wiper arm onto the drive head, tighten the hex screw and replace the cover.
10. Place the protective grilles on the air intake.
11. Close the hood and check the operation of the windshield wiper.
