Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat, stable surface.

2. Check and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the windshield wiper fuse using a fuse puller or pliers.
Inspect the fuse for any breaks in the filament.
Replace with a new fuse of the same amperage if necessary.

3. Inspect and Clean Connections

Reconnect the battery terminal temporarily.
Check the wiring harness and connectors leading to the wiper motor.
Clean any corrosion using electrical contact cleaner and a wire brush.
Ensure all connectors are securely attached.

4. Test and Replace Wiper Motor (if necessary)

If the wiper motor did not operate during the initial test, disconnect the motor from the wiring harness.
Connect the motor directly to a 12V battery to see if it operates.
If it does not work, replace the wiper motor with a new unit.
- To remove the motor, unscrew any mounting bolts and disconnect the wiper linkage if necessary.
- Install the new motor by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications.

5. Final Setup

Reconnect all components and wiring to ensure proper function.
Reconnect the negative battery terminal.
