To begin the front wiper motor assembly process, pry off the protective caps over the wiper arm nuts to access each retaining nut, then remove the nuts that attach the wiper arms to their splined shafts. Mark the position of each wiper arm in relation to its shaft before removing the arms; if they are difficult to detach, use a small two-jaw puller. Next, remove the cowl cover, release the lock on the wiper module electrical connector, and disconnect it from the wiper motor by pushing the lock up and depressing the release tab. Disconnect the windshield washer hose from the coupling outside the wiper assembly, ensuring to inspect the condition of both hoses and the plastic coupling. Disconnect the drain tubes from the pipes on the bottom of the wiper assembly by twisting a screwdriver between the ratcheting teeth to spread the clamp apart. Remove the nuts that attach the wiper assembly support brackets to the welded studs on the upper edge of the firewall, followed by the bolts that attach the wiper assembly to the firewall. Lift the wiper assembly off the welded studs and place it on a clean workbench. Detach the wiper links from the wiper motor crank arm without removing the crank arm from the motor, then disconnect the electrical connector from the wiper motor. Remove the nuts that attach the two middle support brackets to the front edge of the windshield wiper motor assembly, swing the support brackets out of the way, and remove the motor mounting bolts to detach the windshield wiper motor. For the rear wiper motor, remove the cap covering the wiper arm retaining nut, then remove the nut and mark the position of the wiper arm in relation to the wiper motor shaft before detaching it. Remove the liftgate trim panel, disconnect the electrical connector from the rear wiper motor by depressing the release tabs, and remove the rear wiper motor mounting bolts to detach the motor. Installation is the reverse of removal for both the front and rear wiper motors.

Disconnect the negative battery cable.

It is important to mark the position of each wiper arm in relation to its shaft before removing them to ensure proper reinstallation.
