Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is turned off and parked on a flat surface.
Disconnect the 12V battery to prevent electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box, typically under the dashboard or in the trunk.
Remove the cover and identify the wiper fuse (refer to the owner’s manual for the exact location).
Use a multimeter to check for continuity; if blown, replace with a new fuse of the same amperage.

3. Check Wiper Control Stalk

Remove the steering column cover using a Torx screwdriver.
Disconnect the wiper control stalk connector.
Use a multimeter to test for continuity when the stalk is engaged; replace if faulty.

4. Test and Replace Wiper Motor

Locate the wiper motor, typically at the base of the windshield.
Disconnect the power connector from the wiper motor.
Use a multimeter to test for voltage at the connector when the wipers are activated.
If voltage is present and the motor does not operate, replace the motor.
To replace, remove the wiper arm (if necessary) using a puller tool, unbolt the motor, and install the new one.

5. Reassemble and Test

Reconnect all components and wiring harnesses.
Reinstall any covers removed during the process.
Reconnect the vehicle battery and perform a function test of the wipers.
