Warnings

Tools required

Parts

• Windshield washer pump × 1 — Use OEM specification
• Washer pump grommet (if damaged) × 1 — Use OEM specification

Fluids

• Windshield Washer Fluid — 3.5 qt

Preparation

1. Park vehicle on level ground and engage parking brake
2. Turn ignition off and remove key
3. Gather all tools and new washer pump before beginning
4. Position drain pan or bucket to catch washer fluid

Procedure

1. 1

   Access the wheel well area
   Turn the steering wheel fully to the right to provide better access to the driver side front wheel well. This will expose the inner fender liner area where the washer reservoir is located.
2. 2

   Remove inner fender liner fasteners
   Using the trim panel removal tool, carefully remove the plastic push pins and fasteners securing the front portion of the driver side inner fender liner. You only need to remove enough fasteners to pull back the liner for access to the washer reservoir, typically 4-6 fasteners in the forward section.
3. 3

   Pull back fender liner
   Gently pull the inner fender liner back and away from the fender to expose the washer fluid reservoir. You may need to flex it carefully to create adequate working space. The white plastic reservoir tank should now be visible.
4. 4

   Locate the washer pump
   Identify the washer pump mounted in the bottom of the reservoir tank. The pump is a cylindrical component with electrical connector on top and outlet hose connection. Note the orientation of the pump and hose routing for reinstallation.
5. 5

   Disconnect electrical connector
   Press the locking tab on the electrical connector attached to the washer pump and pull the connector straight off the pump. You may need to use needle nose pliers to access the release tab depending on working space.
6. 6

   Disconnect outlet hose
   Using needle nose pliers, carefully squeeze the hose clamp on the pump outlet and slide it back along the hose. Pull the washer hose straight off the pump outlet fitting. Position your drain pan to catch fluid that will drain from the hose and reservoir.
7. 7

   Remove washer pump from reservoir
   Grasp the washer pump firmly and rotate it counterclockwise approximately 1/4 turn while pulling outward to release it from the reservoir grommet. The pump uses a bayonet-style mounting that twists and pulls out. Washer fluid will drain from the reservoir opening, so have your drain pan positioned to catch it.
8. 8

   Inspect and remove grommet
   Inspect the rubber grommet seal in the reservoir where the pump was mounted. If the grommet is cracked, hardened, or damaged, remove it by pulling it out of the reservoir hole. Clean the mounting hole area if debris is present.
9. 9

   Install new grommet if needed
   If the grommet was damaged and removed, press the new grommet firmly into the reservoir mounting hole. Ensure it is fully seated and flush with the reservoir wall before proceeding.
10. 10

    Install new washer pump
    Insert the new washer pump into the reservoir grommet, aligning the pump tabs with the grommet slots. Push the pump in firmly and rotate clockwise approximately 1/4 turn until the pump locks into place. The pump should be secure and not able to pull out when properly locked.
11. 11

    Reconnect outlet hose
    Push the washer hose firmly onto the pump outlet fitting until it bottoms out. Slide the hose clamp forward over the connection point to secure the hose. Ensure the clamp is positioned properly over the hose on the fitting.
12. 12

    Reconnect electrical connector
    Push the electrical connector onto the washer pump terminals until you hear or feel it click into place. Tug gently on the connector to verify it is fully locked.
13. 13

    Reinstall fender liner
    Position the inner fender liner back into its original location against the fender. Reinstall all plastic push pins and fasteners that were removed, ensuring each is fully seated and secure.
14. 14

    Refill washer fluid reservoir
    Open the hood and locate the washer fluid filler cap. Add windshield washer fluid to the reservoir until it reaches the full mark, approximately 3.5 quarts total capacity. Do not overfill.

Reassembly

1. Ensure all fender liner fasteners are properly installed and secure
2. Verify washer fluid reservoir is filled to proper level
3. Check that all electrical connections are locked in place

Verification

• Turn the ignition to ON position without starting the engine
• Activate the windshield washer spray function and verify both washer nozzles spray properly
• Listen for normal pump operation without unusual noise or grinding
• Check for leaks around the pump connection and hose connections while spraying
• Inspect the wheel well area for any washer fluid drips after testing
• Verify spray pattern is adequate and reaches the windshield properly
