Solution

1. Preparation

Gather tools and parts necessary for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine bay).
Identify the wiper motor fuse using the diagram on the fuse cover.
Remove the fuse with a fuse puller or pliers.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace Wiper Motor

If the fuse is intact, locate the wiper motor (typically found under the cowl panel).
Disconnect the electrical connector from the wiper motor.
Use a multimeter to check for voltage at the connector when the wipers are activated.
If no voltage is present, inspect wiring for breaks or shorts.
If voltage is present and the motor does not operate, replace the wiper motor.
- Remove the wiper arms by loosening the nuts and lifting them off.
- Unscrew and remove the mounting bolts for the motor.
- Install the new motor by reversing the process and torque the bolts to the manufacturer’s specifications.

4. Check Wiper Linkage

Inspect the wiper linkage for any disconnections or damage.
If the linkage is damaged, replace it following the same removal and installation process as the motor.
