Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Gather necessary tools and parts before starting the repair.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or near the driver's side).
Remove the wiper fuse using a fuse puller or pliers.
Inspect the fuse for a break in the filament.
If the fuse is blown, replace it with a new fuse of the same amperage (usually 10A or 15A).

3. Replace the Wiper Relay

Identify the wiper relay in the fuse box (refer to the fuse box diagram).
Remove the wiper relay by pulling it straight out.
Insert a new or known working relay into the corresponding slot.

4. Test and Replace the Wiper Motor

Disconnect the wiper motor's electrical connector.
Using a multimeter, check for voltage at the motor connector while the wiper switch is activated.
If no voltage is present, focus on the switch and wiring. If voltage is present but the motor does not operate, replace the wiper motor.
To replace the motor, remove any retaining screws, disconnect the linkage, and pull the motor out.
Install the new motor by reversing the removal steps, ensuring all connections are secure.

5. Reassemble and Clean Up

Reconnect the battery if it was disconnected.
Test the wipers to ensure they function properly.
Ensure all tools are removed from the engine bay and vehicle interior.
