Warnings

Tools required

Parts

• Front wiper motor assembly × 1 — Motorcraft WM-2107 or equivalent
• Wiper motor linkage clip (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key
3. Open hood and secure with prop rod
4. Disconnect negative battery terminal and secure away from battery post
5. Allow engine to cool if recently operated

Procedure

1. 1

   Remove cowl vent screen
   Remove the plastic cowl vent screen (windshield wiper cowl) by removing the push-pin fasteners and screws along the cowl. There are typically 8-10 fasteners securing this panel. Gently lift the cowl panel starting from one side and work across to release any remaining clips. Set aside in a safe location.
2. 2

   Disconnect washer hose
   Locate the windshield washer hoses connected to the washer nozzles integrated into the cowl. Squeeze the retaining tabs and disconnect the hose from the nozzles. You may need to drain some washer fluid into a container. Have shop towels ready to catch any spills.
3. 3

   Disconnect wiper motor electrical connector
   Locate the wiper motor electrical connector on the passenger side of the wiper motor assembly. Press the locking tab and pull the connector straight off the motor. The connector has a weather seal that may require some wiggling to release.
4. 4

   Disconnect wiper linkage from motor arm
   Locate where the wiper linkage connects to the wiper motor output arm. Use a small flathead screwdriver to carefully pry the linkage clip off the ball socket. Do not force - work the clip gently to avoid breaking it. Note the orientation of the linkage for reassembly.
   ⚠The linkage clip is plastic and breaks easily - gentle pressure only.
5. 5

   Remove wiper motor mounting bolts
   Remove the three 10mm mounting bolts securing the wiper motor assembly to the cowl structure. These bolts are typically located around the perimeter of the motor mounting bracket. Keep track of any ground straps attached to these bolts.

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

   Remove wiper motor assembly
   Carefully lift the wiper motor assembly out of the cowl area. You may need to angle it slightly to clear any obstructions. Inspect the mounting area for any corrosion or debris and clean if necessary before installing new motor.
7. 7

   Install new wiper motor
   Position the new wiper motor assembly into the cowl mounting location. Align the motor mounting holes with the cowl structure. Ensure any ground straps are positioned correctly between the motor bracket and mounting surface.
8. 8

   Install and torque mounting bolts
   Install the three 10mm mounting bolts hand-tight first to ensure proper alignment. Once all bolts are started, torque them in a star pattern to specification. Ensure ground straps are making clean metal-to-metal contact.

   Module Mounting Bolts8 Nm (6 lb-ft)

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

   Connect wiper linkage to motor arm
   Align the wiper linkage ball socket with the motor output arm. Press the linkage clip firmly onto the ball socket until you hear or feel it click into place. Verify the connection is secure by attempting to pull the linkage off - it should not release without pressing the clip.
10. 10

    Connect electrical connector
    Push the wiper motor electrical connector firmly onto the motor terminals until the locking tab clicks into place. Ensure the weather seal is properly seated. Gently tug on the connector to verify it is locked.
11. 11

    Reconnect washer hose
    Reconnect the windshield washer hose to the nozzles. Push firmly until the hose is fully seated and the retaining tabs lock into place. Check that the connection is secure.
12. 12

    Reinstall cowl vent screen
    Position the cowl vent screen back onto the vehicle, ensuring all alignment tabs are properly located. Install all push-pin fasteners and screws. Work from one side to the other, ensuring the panel sits flush against the cowl.
    Torque spec

    Cover Screws14 Nm (10 lb-ft)
13. 13

    Reconnect battery
    Reconnect the negative battery terminal. Clean the terminal post and cable clamp if necessary before reconnecting. Torque the terminal bolt to specification.
    ⚠Do not overtighten battery terminal - this can damage the terminal or cable clamp.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

1. Ensure all cowl fasteners are properly secured before operating wipers
2. Verify washer hose connections are tight to prevent leaks
3. Check that wiper linkage connection is secure to prevent wiper system failure

Verification

• Turn ignition to ON position (engine does not need to run)
• Test wiper operation in all speed settings (intermittent, low, high) - wipers should move smoothly without binding or unusual noise
• Test windshield washer function - fluid should spray properly and wipers should activate
• Verify wipers park in correct position when turned off
• Check for any washer fluid leaks around hose connections
• Listen for any unusual noises during operation that might indicate improper linkage connection
