Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is in park and power is turned off for safety.

2. Inspect and Replace the Wiper Fuse

Locate the Fuse Box: Refer to the owner’s manual to find the location of the fuse box.
Remove the Fuse Panel Cover: Carefully take off the cover to access the fuses.
Identify the Wiper Fuse: Use the diagram on the fuse box cover to locate the wiper fuse.
Check the Fuse: Pull the fuse using fuse puller or pliers; inspect it for continuity.
Replace if Necessary: If blown, replace it with a fuse of the same amperage rating (usually 10A for wipers).
Reassemble the Fuse Box: Reattach the cover securely.

3. Inspect the Wiper Motor

Access the Wiper Motor: Remove the wiper arms by loosening the nuts with a socket set and lifting them off.
Disconnect the Wiper Motor Connector: Unplug the electrical connector to the wiper motor.
Test the Motor: Use a multimeter to check for voltage at the connector while activating the wiper switch.
Replace the Motor if Necessary: If no power is detected, or if the motor is faulty, replace it with a new wiper motor.
Reassemble the Wiper Components: Reattach the wiper arms and secure the nuts.
