Solution

1. Preparation

Gather tools and parts.
Safety gear: gloves and safety glasses.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse for the wiper system using the diagram on the fuse box cover.
Remove the fuse with a fuse puller and inspect it. If blown, replace it with a new fuse of the same amperage.
Reconnect the battery terminal.

3. Test Wiper Motor

Disconnect the wiper motor connector.
Using a multimeter, check for voltage at the connector while activating the wiper switch.
- If voltage is present, the motor is likely faulty and needs replacement.
- If no voltage, investigate wiring issues or faulty switch.

4. Replace Wiper Motor (if necessary)

Remove the wiper arms by unscrewing the nuts at the base (use a socket set).
Detach the wiper motor from its mounting location.
Connect the new wiper motor to the wiring harness and secure it in place.
Reattach the wiper arms, ensuring they are correctly aligned.

5. Reassemble and Test

Reconnect the negative battery terminal.
Test the wipers at various speeds and functions to ensure they are operating correctly.
