Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shock.

Tools Required:

Socket set
Multimeter
OBD-II scanner
Screwdrivers (flathead and Phillips)
Pliers

2. Check and Replace the Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.

3. Inspect and Test the Wiper Motor

Reconnect the battery.
Activate the wiper switch to the on position.
Use a multimeter to check for voltage at the wiper motor connector.
- If voltage is present but the motor does not operate, replace the wiper motor.
- If no voltage is present, further inspection of the wiring and switch is needed.

4. Replace the Wiper Motor (if needed)

Remove the wiper arms by loosening the nuts at the base of each arm.
Disconnect the wiper motor's electrical connector.
Unbolt the wiper motor from its mounting bracket.
Install the new wiper motor in reverse order of removal, ensuring proper torque on mounting bolts.

5. Reassemble and Test

Reattach the wiper arms to their respective positions and secure them.
Reconnect the battery.
Test the wipers in all settings to ensure proper operation.
