Removing rear windshield wiper arm on 94 4Runner

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.

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.

if the nozzles are not on the hood, they may be in the wiper arms themselves, I have seen them under the vent grille at the bottom of the windshield as well, you should be able to see the hoses under the hood at the base of the windshield

I took it to a mechanis, who is a friend of mine. Toyota made that rear windshield wiper custom. So he took off the stopper and the screw in lock and I bought a 13" blade and we put the attachment on that came wih the wiper and slid it on to the arm.

remove the cover cap that is by the base of the wiper arm. you can do this by just pulling off with your fingers. The wiper arm is attached with a 10mm nut. remove th nut and the wiper arm will slip off. When re-assembling, be certain to wipe all parts with a long lasting lubricant, like WD40.

1) listen if windshield wiper motor is turning when switched on. The motor is under hood up near firewall.
If no noise and fuses are OK, motor may need replacement.

2) If motor can be heard whirring, then maybe the plastic link between the motor shaft and the wiper arm assy has worn or broken. (A very cheap part). This can be accessed by removing cowling or vents in front of windshield. This is a common failure.
