Windscreen Wiper/Cowl Cover Drive Mechanism — Removal and Installation (BMW 7 Series E32)

Removal

Mark the position of the windshield wiper arms on the windshield by sticking pieces of tape onto the glass near the arms.

Pull or pry the covers off the mounting nuts with a small screwdriver.



Unscrew the nuts.



Pull both wiper arm rods together.

Caution: Do not bend the levers when doing this. To make it easier to remove the levers, it is better to use a suitable puller.

Unhook the left lever cover upwards.

Loosen the nut on the arm support and pull the wiper arm up.

Remove the adjusting washer from the support. This washer is very tightly seated, so a suitable puller is required to remove it.

Pull the rubber seal up from the engine compartment bulkhead. Disconnect the clamps on the air ducts on the left and right.

Rotate the air ducts towards the center line of the car, thus releasing them from their mountings, and remove them.

Remove the left and right cabin air filter elements.

Pull the wire clip out to the side. Unhook the filter housing from the back and remove it.

Remove the fairing cover. To do this, release the eight sliding rivets (clips): unscrew the sliding pins with a screwdriver and pry up the clamps.

Unscrew the screws and remove the cover of the wiper rod.

Remove the wire cover by first turning all the fasteners 90°.

Release the plug and remove it. To do this, slide the fastening latch downwards so that the plug moves away from the contacts.

Remove the five windshield wiper drive mounting bolts (wiper consoles) and remove the drive.

Installation

Insert the wiper drive (console) and tighten the mounting bolts. At the same time, align the drive so that it stands without tension.

Tighten the windscreen wiper drive (A) in sequence from 1 to 5 to a torque of 10 Nm.



Install the plug, insert the latch from the side and press the plug onto the contacts.



Install the wire cover and secure it by turning the four fasteners.

Further installation is carried out in the reverse order of removal.
