Rear windshield wiper does not cover the intended area how to remove rear windshield wiper arm

The wiper motor on a Volkswagen is an electric motor connected through a drive linkage to the wiper arms. Windshield wipers are an integral feature for operating a motor vehicle safely. If your wipers are not functioning, or seem to lack the speed or power they used to have, the wiper motor should be removed and replaced immediately
.

Location

• The wiper motor on a Volkswagen is located directly underneath the plastic cowl cover. The cowl cover is located directly below the windshield.
  

Removal

• Begin by removing the wiper arms by prying off the covers at the base of the arms and removing the nuts that secure the arms to the drive shafts. Label the passenger and driver arms so they can be installed in the same positions. They are not interchangeable. Remove the rubber hood to cowl weather seal. Unscrew the plastic fasteners from the driver's side of the cowl cover, then remove this half of the cover. Remove the fasteners from the passenger's side cowl cover and remove this half of the cover. Disconnect the windshield wiper motor wiring harness by separating the plastic wiring connector. Remove the three bolts that secure the wiper motor to the vehicle's body. Pull the motor slightly away from the body, then remove the nut that connects the motor shaft to wiper linkage. Remove the motor.
  

Installation

• Place the new wiper motor into position in the cowl and reconnect it to the wiper arm linkage. Then reinstall the three retaining bolts. Reconnect the plastic wiring connector to the wiper motor wiring harness. Place the cowl covers into position below the windshield and reinstall the plastic fasteners that retain them. Reinstall the rubber hood to the cowl weather seal. Reinstall the wiper arms in the same position you removed them from, along with the wiper arm retaining nuts and lower wiper arm covers. Turn the windshield wipers on and test for proper operation. If the wiper blades slap against the bodywork surrounding the windshield, loosen the nuts that connect the wiper arms to the shafts and adjust.

Hello: lift/remove cover from the lower end of the w/w arm (toward bottom of windshield) there should be a 13mm nut that attaches the arm to the transmission shaft. Use a 13mm box end and see if the nut is tight. If not tight position the arm in the proper position and tighten nut, re-install nut cover.

why do you think the motor still works if the wipers don't move? Can you hear the motor run or can you see a little movement when you turn the switch on?

What happens when you activate the washers?

go to a salvage yard that allows you to remove the parts yourself. Then you can see how the motor and linkage assembly comes out.
