Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to avoid electrical shock.
Allow the vehicle to cool if it has been recently driven.

2. Inspect and Replace Fuses

Locate the fuse box in the front trunk area.
Remove the cover and locate the wiper fuse using the diagram.
Pull the fuse using a fuse puller or pliers and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage.

3. Wiper Motor Inspection

Remove the wiper arms by loosening the retaining nuts using a socket set.
Carefully pull the wiper arms off the splines without damaging the motor.
Disconnect the wiper motor's electrical connector.
Use a multimeter to check for voltage at the motor connector when the wipers are activated.
If no voltage is detected, check wiring for continuity; if voltage is present but the motor doesn’t operate, replace the wiper motor.

4. Reassemble

Reconnect the wiper motor and install the wiper arms back onto the splines.
Tighten the retaining nuts securely to the manufacturer’s specified torque (typically around 15-20 ft-lbs).
Reconnect the vehicle battery and test the wipers.
