Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the ignition is off.
Disconnect the negative battery terminal to avoid electrical shock.

2. Inspect and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Using a fuse puller, remove the wiper fuse (consult the owner’s manual for the exact fuse location).
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Wiper Motor

Reconnect the negative battery terminal.
If the wipers still do not operate, locate the wiper motor, usually mounted near the base of the windshield.
Disconnect the motor connector and apply direct power from the battery to the motor terminals.
- If the motor operates, it needs replacement.
- If it does not operate, proceed to remove the motor.
Remove the wiper arm by loosening the retaining nut and pulling it off the spline.
Unscrew the mounting bolts securing the wiper motor and carefully remove it.
Install the new wiper motor by reversing the removal steps, ensuring it is securely bolted.

4. Check and Repair Wiper Linkage

Inspect the wiper linkage for any disconnections, bent arms, or excessive wear.
If damaged, replace the linkage assembly.
Reconnect all components, ensuring proper alignment.

5. Test Wiper Operation

Reconnect the negative battery terminal.
Turn on the ignition and test the wipers for proper function across all settings.
