Have taken off 12mm nut on windshield wiper arm, but can't figure out how to pull off windshield wiper arm. There seems to be a washer under the nut, but not sure if there is a special trick to use in getting it off.
Wiggle the arm back and forth when holding it up
SOURCE: windshield wiper arms move all ove rthe windshield incosistently
turn your wipers on and turn the key off when the are about 1/4 to half way up on the winshield and try to pull them one way or the other and see if they move
It really sounds like the wiper transmission arm has gotten stripped the only to fix it is to replace trasmission arm assembly you can get them from your local junk yard cheap!
generally where wiper arms push on there is an additiona part you will have to pull off in order to change the wiper arm assembly

Before you go through the time and hassle of removing the motor itself, spray some WD-40 or something similar on the shaft that goes to the motor...could be the weather seal is dried and squeaking.
The wiper motor on a Volkswagen is located directly underneath the plastic cowl cover. The cowl cover is located directly below the windshield.
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.
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.
