Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, flathead screwdriver, trim removal tool.
Disconnect the vehicle's 12V battery to ensure safety during repairs.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the front trunk.
Use the fuse puller tool to remove the wiper fuse.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.

3. Inspect and Repair Wiring

Reconnect the battery.
Remove the wiper arm covers by gently prying them off with a trim removal tool.
Check the wiring harness connected to the wiper motor for any signs of wear or damage.
Repair or replace any damaged wires, ensuring proper insulation and secure connections.

4. Test and Replace Wiper Motor (if necessary)

Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the connector when the wipers are activated.
If no voltage is present, further investigate the switch; if voltage is present, replace the wiper motor.
To replace, remove the wiper motor by unscrewing the mounting bolts.
Install the new motor in reverse order and reconnect the wiring.
