Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in park and power is off.
Disconnect the 12V battery to prevent electrical short circuits.

2. Inspect and Replace Fuse

Tools Required:
- Fuse puller or needle-nose pliers
Locate the fuse box, typically under the dashboard or in the front trunk.
Identify the fuse for the windshield wipers (refer to the owner's manual).
Remove the fuse and inspect it for continuity. Replace if blown with an identical-rated fuse (usually 15A or 20A).

3. Check Wiper Motor and Connections

Tools Required:
- Socket set
- Multimeter
Locate the wiper motor, usually at the base of the windshield.
Disconnect the electrical connector from the motor.
Use a multimeter to test for voltage at the connector while activating the wiper switch.
If no voltage is present, trace wiring back to the fuse box for faults.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Inspect and Replace Wiper Blades

Tools Required:
- None specifically needed
Remove old wiper blades by releasing the clips or sliding them off the arm.
Install new wiper blades, ensuring they are securely fastened.

5. Test Windshield Washer System

Tools Required:
- None specifically needed
Reconnect the battery.
Fill the wiper fluid reservoir if low.
Activate the washer switch to ensure fluid sprays correctly and the pump operates.
