Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the vehicle's battery to prevent any electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box (refer to the vehicle manual for the exact location).
Remove the wiper fuse using a fuse puller or pliers.
Check the fuse for continuity; replace it if it is blown with a new fuse of the same amperage.
Reinstall the fuse and reconnect the battery.

3. Test the Wiper Motor

Reconnect the vehicle's battery.
Activate the wiper switch to the on position.
Using a multimeter, check for voltage at the wiper motor connector.
- If no voltage is present, trace back to the switch and wiring.
- If voltage is present, proceed to the next step.

4. Replace the Wiper Motor (if necessary)

Remove any covers or panels obstructing access to the wiper motor.
Disconnect the wiring harness from the wiper motor.
Remove the mounting bolts securing the wiper motor to the vehicle.
Install the new wiper motor by reversing the removal steps.
Reconnect the wiring harness and any covers or panels.
