Solution

1. Preparation

Tools Required: Wrench set, OBD-II scanner, multimeter, flathead screwdriver, socket set, replacement wiper blades, electrical cleaner.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Wiper Blades

Remove the wiper blades by lifting the arm away from the windshield and pressing the release tab.
Slide the old blades off the arm and attach the new blades by sliding them into place until they click securely.
Lower the wiper arms back onto the windshield.

3. Check and Replace the Wiper Motor

Locate the wiper motor (typically under the cowl panel at the base of the windshield).
Disconnect the wiring harness from the motor and remove the mounting bolts using a socket set.
Pull the motor out and replace it with a new one, ensuring to reconnect the wiring securely and tighten the mounting bolts to the manufacturer's torque specifications (usually around 20-25 ft-lbs).

4. Replace the Wiper Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the wiper fuse (refer to the owner's manual for the exact location).
Remove the blown fuse and replace it with a new fuse of the same amperage (typically 10-15 amps).

5. Reassemble and Test

Reconnect the negative battery terminal.
Test the wipers by engaging the control to ensure proper operation and that they return to the parked position.
