Tools required

Parts

• Front wiper motor assembly × 1 — Use OEM specification
• Cowl panel clips (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Mark wiper blade positions at rest on windshield with tape for reinstallation reference
3. Open hood and secure with prop rod
4. Disconnect battery negative terminal and secure cable away from battery post
5. Wait minimum 2 minutes for airbag system to discharge

Procedure

1. 1

   Remove wiper arms
   Lift wiper arm away from windshield and locate the release tab or nut at base of arm. If equipped with release tab, press tab and pull arm off splined shaft. If equipped with retaining nut, use 13mm socket to remove nut, then wiggle arm while pulling away from cowl to remove from splined shaft. Remove both driver and passenger wiper arms.
2. 2

   Remove cowl panel grille
   Remove the plastic cowl vent grille panel that runs along the base of the windshield. Use trim panel removal tool to carefully pry up and release the retaining clips starting from one end. Work along the entire length, releasing each clip. Once all clips are released, lift the cowl panel up and away from the firewall. Disconnect any washer hoses if attached to the panel.
3. 3

   Access wiper motor mounting area
   With cowl removed, locate the wiper linkage assembly and motor on the driver side of the cowl area. Remove any plastic covers or shields that obstruct access to the wiper motor mounting bolts. On some models, a plastic access cover is secured with clips or screws that must be removed.
4. 4

   Disconnect wiper motor electrical connector
   Locate the electrical connector on the wiper motor assembly. Press the locking tab and pull connector straight away from motor. Ensure connector is completely disconnected and positioned away from work area.
5. 5

   Remove wiper linkage arm from motor
   Locate the wiper linkage arm connection to the motor crank arm. Use 10mm socket to remove the retaining nut securing the linkage to the motor crank arm. Carefully separate the linkage arm from the motor crank. Support the linkage to prevent it from falling.
6. 6

   Remove wiper motor mounting bolts
   Using 10mm socket, remove the three mounting bolts securing the wiper motor to the cowl support bracket. Support the motor while removing the final bolt to prevent it from dropping. Carefully maneuver the motor out of the cowl area, taking care not to damage surrounding components.
7. 7

   Install new wiper motor
   Position new wiper motor into mounting location in cowl area. Align motor with mounting holes on support bracket. Hand-thread all three mounting bolts before tightening any. Torque mounting bolts to 8.0 Nm (6 lb-ft) in a cross pattern to ensure even seating.

    Reinstall wiper arms
    Before installing wiper arms, reconnect battery negative terminal and torque to 6.0 Nm (4 lb-ft).

Reassembly

1. Ensure all cowl panel clips are fully engaged and panel is secure
2. Verify wiper arms are aligned with original positions marked on windshield
3. Double-check all electrical connections are secure and locked
4. Confirm no tools or parts are left in cowl or engine bay

Verification

• Turn ignition to ON position and test wipers in all speed settings (intermittent, low, high)
• Verify wipers park correctly in rest position when turned off
• Check for proper wiper blade contact across full windshield sweep
• Test washer function to ensure spray pattern is correct and wipers activate
• Listen for any unusual noises during wiper operation that might indicate binding or misalignment
• Verify wiper arms do not contact hood or cowl at any point in their travel
