Removal and installation of levers (leashes) of screen wipers

Windshield

Withdrawal

1. Wash the windshield, turn the wipers on and off again, they should be in the lowest position.

2. Mark the position of the rubber wiper blades by sticking adhesive tape or duct tape along the wiper blade on the windshield.

3. Open the hood.

4. Pry off the protective cap with a screwdriver (see resist. illustration) and remove it from the arm axle spindle.

Note: On Astra models equipped with a screw cap, unscrew it by hand until there is sufficient clearance between the cap and the lever.

5. Loosen the fixing nut (see illustration 9.4) about 2 turns. Slightly rocking the wiper arm from side to side, pull the wiper arm off the axle spindle seat, using a suitable tool if necessary. Service stations use a special tool HAZET 779-18 (see resist. illustration).



6. Completely turn away a nut and remove the screen wiper arm from a spindle.

Note: On some models, a washer may be installed on the lever axle (see illustration 9.4), remember its position and do not forget to put it on when installing the lever.

Installation

7. Make sure that the position of the wiper drive corresponds to the extreme position, if necessary, turn on the drive and set the desired position.

8. Install the lever on the spindle seat so that the wiper blade is aligned with the previously applied adhesive tape (tape).

9. Tighten the arm mounting nut by hand. Close the hood, wash the windshield and after a while turn on the wipers - during operation, the wiper blades should not go beyond the glass, and when the drive is turned off, they should return to their lowest position. Otherwise, loosen the nut and repeat the installation of the corresponding lever.

10. After adjustment is complete, tighten the fixing nuts to the required torque and replace the protective caps.
