Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is turned off and parked on a flat surface.
Disconnect the negative terminal of the battery for safety.

2. Check and Replace Fuse

Locate the fuse box (refer to the owner's manual for exact location).
Identify the fuse for the windshield wipers and remove it using a fuse puller.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

If the wiper motor does not operate after applying direct power, it may need replacement.
Remove the wiper arm(s) using a socket set to expose the motor.
Disconnect the wiring harness from the wiper motor.
Remove the mounting bolts and take out the old motor.
Install the new motor by reversing the removal process and reconnecting the wiring harness.
