Tools required

Parts

• Front wiper motor assembly × 1 — Use OEM specification
• Wiper motor connector seal × 1 — Replace if damaged
• Cowl panel clips × 5 — Have extras on hand

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key
3. Allow engine to cool if recently driven
4. Mark wiper blade resting positions with tape on windshield for reference
5. Disconnect negative battery terminal and wait 3 minutes for airbag system to discharge

Procedure

1. 1

   Remove wiper arms
   Lift the wiper arm away from the windshield. Remove the plastic cap covering the wiper arm nut. Use a 14mm socket to loosen and remove the wiper arm mounting nuts. Mark the orientation of each wiper arm on the splined post with a marker. Use gentle rocking motion or a wiper arm puller to remove both wiper arms from their posts.
2. 2

   Remove cowl cover panel
   Open the hood. Remove the rubber weatherstrip from the cowl area by pulling it out of its retaining clips. Locate and remove the plastic clips securing the cowl cover panel (typically 6-8 clips). Use trim panel removal tools to carefully pry up the cowl cover panel starting from one end and working across. Disconnect the washer nozzle hoses from underneath the cowl if equipped.
3. 3

   Access wiper linkage and motor
   With the cowl panel removed, you will see the wiper linkage assembly and motor. Clear any debris or leaves from the wiper motor area. Locate the wiper motor electrical connector on the passenger side of the linkage assembly.
4. 4

   Disconnect wiper motor electrical connector
   Press the locking tab on the wiper motor electrical connector and carefully disconnect it from the motor. Inspect the connector seal for damage or deterioration and replace if necessary. Secure the wiring harness away from the work area.
5. 5

   Remove wiper linkage mounting bolts
   Locate the three mounting bolts securing the wiper linkage assembly to the cowl structure. Use a 10mm socket to remove these bolts. Note the position of any ground straps or brackets attached to these mounting points for proper reassembly.
6. 6

   Remove wiper motor and linkage assembly
   Carefully lift the entire wiper motor and linkage assembly out of the cowl area. The assembly is removed as a complete unit. Maneuver the linkage arms to clear any obstructions. Place the assembly on a clean work surface.
7. 7

   Separate wiper motor from linkage
   On the work surface, locate the three bolts securing the wiper motor to the linkage bracket. Use a 10mm socket to remove these bolts. Note the orientation of the motor crank arm relative to the linkage. Carefully separate the motor from the linkage assembly, supporting the linkage to prevent it from springing apart.
8. 8

   Install new wiper motor
   Position the new wiper motor to the linkage assembly, ensuring the motor crank arm engages properly with the linkage. Align the mounting holes and install the three motor mounting bolts. Torque the bolts to specification. Verify the linkage moves smoothly through its full range of motion.

   Module Mounting Bolts8 Nm (6 lb-ft)
9. 9

   Install motor and linkage assembly
   Carefully lower the wiper motor and linkage assembly into the cowl area. Align the mounting holes with the cowl structure. Install the three mounting bolts and torque to specification. If a ground strap was present, ensure it is positioned correctly under the bolt.
   Torque spec

   Ground Strap Bolts12 Nm (9 lb-ft)
10. 10

    Reconnect electrical connector
    Connect the wiper motor electrical connector to the motor, ensuring it clicks into place securely. Verify the connector lock tab is fully engaged. Check that the connector seal is properly seated to prevent water intrusion.
11. 11

    Reinstall cowl cover panel
    Reconnect the washer nozzle hoses if they were disconnected. Position the cowl cover panel and press down firmly to engage all retaining clips. Replace any damaged clips with new ones. Reinstall the rubber weatherstrip along the cowl edge, ensuring it seats properly in all retaining clips.
12. 12

    Reinstall wiper arms
    Reconnect the negative battery terminal and torque to specification. Turn the ignition on and activate the wipers to cycle the motor to the park position, then turn the ignition off. Position each wiper arm on its splined post according to your original marks. Install the wiper arm nuts and torque to specification. Install the plastic caps over the nuts.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. Ensure all electrical connectors are fully seated and locked
2. Verify all cowl panel clips are properly engaged before testing
3. Check that washer nozzles are properly connected and aimed correctly
4. Confirm wiper arms are in correct park position before final tightening

Verification

• Reconnect battery and reprogram power window auto-up/down feature by fully opening and closing each window
• Turn ignition on and test wiper operation in all speeds (intermittent, low, high)
• Test wiper park function - wipers should return to proper rest position
• Verify washer fluid sprays properly and wipers activate with washer function
• Check for any unusual noise, binding, or abnormal movement during operation
• Inspect for any fluid leaks around cowl area after testing
• Verify wiper blades make full contact with windshield across entire sweep area
