2. Check and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the trunk.
Identify the fuse related to the wiper motor (refer to the owner's manual for location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity using a multimeter; replace it if necessary.

3. Inspect and Test the Wiper Motor

Reconnect the battery temporarily.
Locate the wiper motor, typically under the cowl panel at the base of the windshield.
Disconnect the wiring harness from the wiper motor.
Using a multimeter, check for voltage at the connector while activating the wiper control stalk.
If voltage is present, the motor may need replacement; if not, further electrical troubleshooting is needed.

4. Replace the Wiper Motor (if required)

Remove the wiper arms by unscrewing the nuts holding them in place and gently lifting them off the splines.
Unscrew the bolts securing the wiper motor and remove any retaining clips.
Disconnect the old motor from the wiring harness.
