Solution

1. Preparation

Gather tools and parts: OBD-II scanner, multimeter, socket set, replacement wiper motor (if needed), and wiper blades.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace the Fuse

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 check for continuity with a multimeter. If blown, replace it with a fuse of the same amperage.

3. Inspect and Replace the Wiper Relay

Locate the wiper relay in the fuse box or relay panel.
Remove the relay and test it for proper operation using a multimeter.
If defective, replace it with a new relay.

4. Test and Replace the Wiper Motor

Disconnect the wiper motor electrical connector.
Use a multimeter to test for power at the connector while activating the wiper switch.
If power is present but the motor does not operate, remove the motor using a socket set.
Install the new motor, ensuring it is properly aligned with the wiper linkage.

5. Inspect the Wiper Linkage

With the wiper motor removed, visually inspect the linkage for any signs of damage or disconnection.
If damaged, replace the linkage assembly.

6. Replace Wiper Blades

Remove the old wiper blades by releasing the clip or tab holding them in place.
Install new wiper blades by sliding them onto the wiper arms until they click securely into place.
