Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, fuse puller.
Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Sub-steps:
1. Locate the fuse box, typically found under the dashboard or in the trunk.
2. Using the fuse puller, carefully remove the wiper fuse (refer to the owner's manual for the exact fuse location).
3. Inspect the fuse for continuity using a multimeter; if it's blown, replace it with a fuse of the same amperage.
4. Reinstall the fuse and reconnect the battery.

3. Test the Wiper Motor

Sub-steps:
1. Reconnect the vehicle's battery.
2. Turn on the ignition and activate the wipers.
3. If the wipers still do not operate, access the wiper motor by removing the cowl panel (if applicable).
4. Check the motor's electrical connector for damage and use a multimeter to test for power at the connector when the wiper switch is activated.
5. If there is no power, trace the wiring back to the control stalk for potential issues.
6. If the motor is receiving power but not functioning, replace the wiper motor.

4. Repair or Replace Control Stalk (if needed)

Sub-steps:
1. Remove the steering column cover (if applicable) to access the wiper control stalk.
2. Disconnect the wiring harness from the control stalk.
3. Test the control stalk with a multimeter to ensure correct resistance values when operated.
4. If faulty, replace the control stalk with a new unit and reconnect the wiring.
