Warnings

Tools required

Parts

• Wiper linkage assembly × 1 — Use OEM specification
• Cowl weatherstrip seal × 1 — Inspect and replace if damaged

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition off and remove key
3. Mark wiper blade rest positions on windshield with masking tape for reference
4. Open hood and secure in upright position
5. Disconnect negative battery terminal and isolate cable away from battery post
6. Wait 3 minutes for airbag system capacitor discharge

Procedure

1. 1

   Remove wiper arms
   Lift the wiper arm away from windshield. Remove the plastic cap covering the wiper arm nut. Use a 14mm socket to loosen and remove the wiper arm mounting nuts. Pull wiper arms straight off the splined shafts using a rocking motion. If stuck, use a wiper arm puller tool to avoid damaging the linkage.
2. 2

   Remove cowl cover weatherstrip
   Starting from one end, carefully pull the rubber weatherstrip seal from the cowl cover. This seal runs along the rear edge of the hood opening. Remove completely and inspect for damage or deterioration.
3. 3

   Remove cowl cover panels
   Locate and remove the plastic clips and screws securing the cowl cover panels. Remove both driver and passenger side cowl covers by lifting up and pulling away from the windshield. These panels cover the wiper linkage area. Note the position of any clips for reassembly.

   Disconnect washer hoses
   Disconnect the windshield washer fluid hoses from the washer nozzles on the cowl. Pull straight off the nozzle barbs. Have a shop towel ready to catch any fluid drips. Move hoses aside for access.
5. 5

   Disconnect wiper motor electrical connector
   Locate the wiper motor electrical connector on the driver side of the linkage assembly. Press the locking tab and disconnect the connector from the wiper motor. Move the wiring harness aside.

   Remove linkage pivot nuts and mounting bolts
   Locate the pivot nuts at each end of the linkage assembly where the wiper arm shafts protrude. Use a 12mm socket to remove these nuts. Then remove the mounting bolts securing the linkage frame to the cowl area using a 12mm or 14mm socket as applicable.

   Remove wiper linkage assembly
   Carefully lift the entire wiper linkage assembly up and out of the cowl area. The assembly may need to be angled or rotated to clear the firewall and cowl structure. Control the linkage as the spring tension releases during removal.
   ⚠Linkage contains internal springs that may shift during removal. Maintain control to prevent pinching fingers or damaging surrounding components.

    Install wiper arms
    Reconnect the negative battery terminal. Turn the ignition to ON (engine off) and activate the wipers using the wiper stalk, then turn off when they reach their parked position. Install the wiper arms onto the splined shafts, aligning with the tape marks on the windshield. Install and tighten the wiper arm nuts securely.

Reassembly

1. Ensure all electrical connections are secure and locked in place
2. Verify cowl covers are properly seated and all clips engaged
3. Check that washer hoses are connected and not kinked
4. Confirm wiper arms are positioned correctly in park position before final tightening

Verification

• Reconnect battery and start engine
• Test wipers at all speed settings (intermittent, low, high) to verify smooth operation without binding or noise
• Activate washer function to confirm washer fluid sprays correctly
• Verify wipers return to proper park position when turned off
• Check for any unusual noises, vibrations, or binding during operation
• Inspect cowl area for any rattles or loose panels while wipers operate
