Solution

1. Preparation

Tools Required: OBD-II scanner (for diagnostics), multimeter, socket set, flathead screwdriver, torque wrench.
Disconnect the vehicle's 12V battery to prevent electrical shock.

2. Check and Replace Fuses

Locate the fuse box; refer to the owner's manual for the exact location.
Identify the fuse for the windshield wipers and remove it using the flathead screwdriver.
Inspect the fuse for continuity; replace it if blown.
Reinstall the fuse and reconnect the battery.

3. Inspect and Test Wiper Motor

Remove the wiper arms by loosening the retaining nuts with a socket set and lifting them off the splines.
Remove any covers or panels obstructing access to the wiper motor.
Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for voltage at the motor connector while engaging the wiper control.
If voltage is present, proceed to test the motor.
If no voltage is detected, trace back to the control stalk and wiring harness for faults.

4. Replace Wiper Motor (if necessary)

If the motor is unresponsive during testing, it may need replacement.
Remove the wiper motor by unscrewing the mounting bolts with a socket set.
Install the new motor by reversing the removal steps and torque the bolts to the manufacturer's specifications.
