  Q: How to Remove and Install a Wiper Motor?

  A: Disconnect the fusible link beneath the hood or detach the battery ground cable. Disconnect the wiper motor wires, then remove the motor mounting screws. Lower the motor far enough to gain access to the crank arm-to-drive link retainer bushing. Remove the crank arm from the drive link by prying the retainer bushing from the crank arm pin with a large screwdriver. Remove the motor, then remove the nut to detach the crank arm from the motor drive shaft. Hold the motor assembly in a vise and remove the housing through-bolts. Remove the housing and armature assembly and take the flat and spring washers off the armature shaft. Examine the parts for wear and damage. Replace parts as necessary. To assemble the motor, install the brushes in their respective slots and retain them by locking the brush lead wires into the notches at the rear of the slots. Clean the commutator using an ink eraser, then install the flat spring, and flat washers on the armature shaft. Install the armature in the bearing while rotating it counter-clockwise to mate the shaft gear with the intermediate gear. Release all the brush wires from the notches and make sure that the springs are exerting tension on them. Align the window in the motor housing with the brush holder and install it quickly over the armature so the magnets in the motor housing don't pull the armature out of the brush housing. Install the through-bolts and washers, and tighten them. Installation of the motor is basically the reverse of the removal procedure. The crank arm pin snaps into the drive link retainer to hold it in place.
