Solution

1. Preparation

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

2. Inspect and Replace the Fuse

Tools: Fuse puller or needle-nose pliers.
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity. Replace it with a new fuse of the same amperage if blown.

3. Test the Wiper Motor

Tools: Jumper wires, multimeter.
Locate the wiper motor, usually at the base of the windshield.
Disconnect the motor's electrical connector.
Use jumper wires to connect the motor directly to the battery. If the motor operates, it is functional; if not, it may need replacement.

4. Check and Repair Wiring

Visually inspect the wiring harnesses connected to the wiper motor and control switch for signs of wear or damage.
Use a multimeter to test for continuity in the wiring.
Repair or replace any damaged wires as necessary.

5. Replace the Wiper Motor (if needed)

Tools: Socket set, torque wrench.
Remove the wiper arm(s) by loosening the nut and lifting them off the splines.
Unscrew the mounting bolts for the wiper motor and disconnect the wiring harness.
Install the new wiper motor by reversing the removal steps. Torque bolts to the manufacturer's specifications.

6. Reassemble and Test

Reattach the wiper arms and ensure they are positioned correctly.
Reconnect the negative battery terminal.
Test the wipers in all modes to confirm functionality.
