Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse for the wipers using a fuse puller.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage (refer to the owner's manual for specifications).

3. Test Wiper Motor

Locate the wiper motor, which is typically found under the plastic cover at the base of the windshield.
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the connector when the wiper switch is activated. If voltage is present, the motor is faulty.
If no voltage is present, trace the wiring back to the fuse box for any breaks.

4. Replace Wiper Motor (if necessary)

Remove the wiper arms using a wiper arm puller if needed.
Unscrew the mounting bolts securing the wiper motor and remove the motor.
Install the new motor in reverse order of removal, ensuring all connections are secure.

5. Reassemble and Test

Reattach the wiper arms to the new motor, making sure they are in the correct position.
Reconnect the negative battery terminal.
Test the wipers by activating the switch to ensure proper function.
