Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Wire connectors
Screwdriver set

2. Check and Replace Fuses

Locate the fuse box (usually found in the glove compartment or under the dashboard).
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller and inspect it. Replace if blown.

3. Inspect and Test the Wiper Motor

Remove the wiper arm by unscrewing the retaining nut.
Disconnect the power connector from the wiper motor.
Use a multimeter to check for voltage at the connector when the wiper switch is activated.
If no voltage is detected, trace back to the relay and check connections.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Replace Faulty Components

If the motor is defective, install the new wiper motor.
Reconnect the power connector and reinstall the wiper arm.

5. Reassemble and Test

Reconnect the battery terminal.
Test the wipers to ensure they operate correctly.
Check the washer fluid function after wiper operation is confirmed.
