Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Prepare a workspace with good lighting and access to the vehicle's interior.

2. Inspect and Replace the Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the windshield wiper fuse using the diagram on the fuse box cover.
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Wiper Motor

Locate the wiper motor, usually found beneath the windshield cowl.
Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for voltage at the motor connector when the wiper switch is activated.
- If voltage is present, the motor is faulty and needs replacement.
- If no voltage, trace the wiring back to the switch for issues.
To replace the motor:
- Remove the wiper arms by loosening the retaining nuts.
- Remove any screws or clips securing the wiper motor to the vehicle.
- Disconnect the motor from the linkage.
- Install the new motor by reversing the removal steps and reconnect the wiring harness.

4. Reassemble and Test

Reattach the wiper arms to their respective locations.
Reconnect the negative battery terminal.
Test the wipers to ensure they operate smoothly without obstruction.
