Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and is powered off.
Disconnect the vehicle battery to prevent electrical shorts.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box, typically under the dashboard or in the trunk area.
Identify the wiper fuse using the fuse diagram located in the owner's manual.
Remove the fuse and check for continuity using a multimeter.
If blown, replace it with a new fuse of the same amperage.

3. Test and Replace Wiper Motor

Tools Required: Socket set, multimeter.
Access the wiper motor by removing the plastic cover from the wiper assembly.
Disconnect the motor's electrical connector and use a multimeter to check for voltage when the wiper switch is activated.
If there is no voltage, inspect the wiring for breaks or shorts.
If voltage is present but the motor does not operate, remove the motor by unscrewing the mounting bolts and replace it with a new unit.

4. Check and Replace Wiper Relay

Tools Required: Socket set.
Locate the relay for the wipers, typically found in the fuse box.
Remove the relay and test it for continuity using a multimeter.
If faulty, replace it with a new relay of the same type.
