Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, pliers)
Disconnect the vehicle's 12V battery to ensure safety during repair.

2. Check and Replace Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the front trunk area.
Identify the wiper fuse using the fuse diagram.
Remove the fuse and inspect it; replace it if blown (ensure to use the same amperage rating).

3. Inspect and Repair Wiring Harness

Visually inspect the wiper motor harness for any signs of damage, corrosion, or loose connections.
If damage is found, repair the wiring by splicing in new wire or replacing connectors as needed.

4. Test Wiper Motor

Disconnect the wiper motor from the harness.
Using jumper wires, connect the motor directly to a power source (ensure correct polarity).
If the motor activates, it may need replacement; if not, it is likely faulty.

5. Replace Wiper Motor (if necessary)

Remove any covers or trim panels to access the wiper motor.
Unbolt the motor from its mounting points and disconnect the wiring harness.
Install the new motor by reversing the removal process, ensuring all connections are secure.
