Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Inspect and Replace Fuse

Locate the fuse box (refer to the owner's manual for location).
Remove the windshield wiper fuse using a fuse puller.
Inspect the fuse; if it is blown, replace it with one of the same amperage.
Reinstall the fuse into the fuse box.

3. Test and Replace Wiper Motor

Locate the wiper motor, which is typically under the windshield cowl.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to test for power at the connector when the wiper switch is activated.
If no power is present, inspect wiring and switch; if power is present, replace the wiper motor.
To replace, unscrew the mounting bolts securing the motor and remove it. Install the new motor and reconnect the electrical connector.

4. Inspect Wiper Relay

Locate the relay associated with the windshield wipers in the relay box.
Remove the relay and inspect for signs of damage.
Swap the relay with a similar one (check the label for compatibility) to test functionality.
If the wipers operate with the new relay, replace the faulty relay.
