Solution

1. Preparation

Gather tools and safety gear.
Ensure the vehicle is turned off and parked on a level surface.
Disconnect the 12V battery to prevent electrical shock.

2. Inspect and Replace Wiper Blades

Tools Required: Flathead screwdriver, replacement wiper blades.
Lift the wiper arms away from the windshield.
Use a flathead screwdriver to release the wiper blades from the wiper arms.
Install the new wiper blades by sliding them into the wiper arms until they click into place.
Lower the wiper arms back onto the windshield.

3. Check and Replace the Wiper Fuse

Tools Required: Fuse puller or needle-nose pliers, replacement fuse (check owner’s manual for specifications).
Locate the fuse box (usually found under the dashboard or in the front trunk).
Remove the cover and identify the wiper fuse using the diagram.
Pull the fuse out and inspect it; if the filament is broken, replace it with a new fuse of the same amperage.
Reinstall the fuse cover.

4. Inspect and Replace the Wiper Motor (if necessary)

Tools Required: Socket set, screwdrivers, multimeter.
Remove the plastic cover from the wiper assembly by unscrewing it.
Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for voltage at the motor connector while the wipers are activated.
If there is no voltage, the issue may be in the wiring or the control module; if voltage is present, replace the wiper motor.
To replace, unscrew the motor from its mounting, install the new motor, reconnect the wiring, and reassemble the cover.
