Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Tools Required: Wrench set, screwdriver set, multimeter, OBD-II scanner, and a fuse puller.

2. Inspect and Replace Fuses

Locate the fuse box as per the vehicle manual.
Identify the wiper fuse and remove it using the fuse puller.
Inspect the fuse for continuity; replace if blown.
Reinsert the new fuse and reconnect the battery.

3. Test the Wiper Motor

Disconnect the wiper motor connector.
Use a multimeter to check for voltage at the motor connector while the wiper switch is activated.
If voltage is present, the motor may be faulty. Replace the motor by:
- Removing any covers or panels obstructing access.
- Unscrewing the motor from its mount.
- Disconnecting the wiper linkage from the motor.
- Installing the new motor in reverse order.

4. Inspect Wiper Linkage

If the motor is functional, check the wiper linkage:
- Remove the wiper arms by loosening the nuts securing them to the motor.
- Inspect the linkage for wear or disconnection.
- Lubricate the linkage if it is stiff or replace if damaged.
- Reassemble the wiper arms and secure them properly.
