Warnings

Tools required

Parts

• Rear wiper motor assembly × 1 — Use OEM specification
• Rear wiper arm nut (if damaged) × 1 — Use OEM specification
• Interior trim clips (as needed for replacements) × 5 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key from vehicle
3. Move rear wiper arm to vertical position for easier access
4. Ensure rear hatch can be fully opened and supported

Procedure

1. 1

   Remove rear wiper arm
   Lift the protective cap at the base of the wiper arm. Use a 14mm socket to remove the wiper arm retaining nut. Mark the position of the wiper arm on the splined shaft with tape or a marker for proper reinstallation alignment. Gently rock the wiper arm while pulling away from the glass to remove it from the splined shaft.
2. 2

   Remove rear hatch interior trim panel
   Open the rear hatch fully. Locate and remove plastic cover caps from the trim panel fasteners using a flathead screwdriver. Remove the trim panel mounting screws using a 10mm socket. Use trim removal tools to carefully release the retaining clips around the perimeter of the trim panel, working from the edges toward the center. Disconnect any electrical connectors for the rear hatch opener or cargo light if equipped. Set the trim panel aside in a safe location.
3. 3

   Disconnect wiper motor electrical connector
   Locate the rear wiper motor electrical connector on the back side of the motor assembly. Press the locking tab and carefully disconnect the wiring harness connector. Ensure you note the connector orientation for reassembly.
4. 4

   Disconnect washer hose (if equipped)
   If your vehicle has a rear washer system, locate the washer fluid hose connected to the wiper motor assembly. Press the locking tabs on the quick-disconnect fitting and pull the hose free. Have a small container or rag ready to catch any residual washer fluid.
5. 5

   Remove wiper motor mounting bolts
   Locate the wiper motor mounting bolts securing the motor assembly to the rear hatch. There are typically three 10mm bolts holding the motor bracket. Remove all mounting bolts and carefully pull the motor assembly away from the hatch. Guide the motor shaft through the hatch opening as you remove the assembly.
6. 6

   Install new wiper motor assembly
   Position the new wiper motor assembly and guide the output shaft through the hatch opening. Align the motor bracket with the mounting holes. Install the mounting bolts finger-tight first to ensure proper alignment, then torque the mounting bolts to specification in a cross-pattern sequence to ensure even seating.

   Module Mounting Bolts8 Nm (6 lb-ft)
7. 7

   Reconnect washer hose and electrical connector
   Reconnect the washer fluid hose to the motor assembly, ensuring the quick-disconnect fitting clicks into place securely. Connect the electrical connector to the wiper motor, pressing firmly until you hear or feel the locking tab engage.
8. 8

   Reinstall interior trim panel
   Reconnect any electrical connectors for cargo lights or hatch release that were disconnected. Align the trim panel with the hatch opening and press firmly to engage the retaining clips around the perimeter. Install the trim panel mounting screws and torque to specification. Reinstall the plastic cover caps over the screw heads.
   Torque spec

   Cover Screws10 Nm (8 lb-ft)
9. 9

   Reinstall wiper arm
   Ensure the wiper motor is in the park position by momentarily turning on the ignition and activating the rear wiper, then turning it off to allow it to return to park. Align the wiper arm with the marks made during removal and press it onto the splined shaft. Install the retaining nut finger-tight, then torque to 13-15 Nm (10-11 lb-ft). Close the protective cap.

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify all trim panel clips are engaged and panel is flush with hatch
3. Confirm wiper arm is properly aligned with park position markers on glass

Verification

• Turn ignition on and test rear wiper operation through all speed settings
• Verify wiper returns to correct park position when turned off
• Test rear washer function (if equipped) and check for leaks at hose connection
• Inspect wiper blade contact with glass through full sweep range
• Check that wiper arm does not contact hatch trim or glass edge
• Verify no rattles or abnormal noises from motor or trim panel
