Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Replace the Wiper Fuse

Locate the fuse box, typically under the dashboard on the driver's side or in the engine compartment.
Identify the wiper fuse using the fuse diagram.
Remove the faulty fuse using a fuse puller.
Replace with a new fuse of the same amperage rating.

3. Inspect and Clean Electrical Connections

Reconnect the battery temporarily.
Examine the wiper motor connector for corrosion or loose wires.
Clean any corroded terminals using a contact cleaner and a wire brush.
Ensure all connections are secure before proceeding.

4. Test and Replace the Wiper Motor (if necessary)

If connections are good, reconnect the battery and test the wipers.
If wipers still do not operate correctly, remove the wiper arm using a socket set.
Unmount the wiper motor from its bracket by removing the retaining screws.
Disconnect the wiring harness and remove the motor.
Install the new wiper motor by reversing the removal steps and ensuring all screws are tightened to the manufacturer’s specification.
