Solution

1. Preparation

Gather tools: socket set, multimeter, screwdriver, and replacement parts if necessary.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box using the owner's manual.
Remove the wiper fuse and inspect it for continuity using a multimeter.
If blown, replace it with a new fuse of the same amperage.

3. Inspect and Test Wiper Motor

Reconnect the battery and turn on the wiper switch to the "on" position.
Use a multimeter to measure voltage at the wiper motor connector (should be around 12V).
If there is voltage and the motor does not operate, proceed to replace the wiper motor.

4. Replace Wiper Motor (if necessary)

Remove the wiper arms by loosening the retaining nuts with a socket.
Disconnect the wiper motor wiring harness.
Remove the mounting bolts securing the wiper motor to the vehicle.
Install the new wiper motor by reversing the removal process, ensuring all bolts are torqued to the manufacturer's specifications.

5. Inspect and Repair Wiper Linkage

If the wiper motor is functional but wipers do not move, check the wiper linkage.
Remove the motor and inspect the linkage for any breaks or disconnections.
Reconnect or replace any damaged components and reassemble.
