Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver, wiring harness repair kit (if needed).
Disconnect the battery negative terminal to avoid electrical shock or short circuits.

2. Remove Wiper Control Switch

Locate the switch: Remove the steering column cover by unscrewing the screws with a socket set.
Disconnect the switch: Carefully pull the wiper control switch out and disconnect the wiring harness.
Inspect the switch: Check for any signs of burning or damage.

3. Test and Replace Wiper Relay

Locate the relay: Access the fuse box, usually located in the engine bay or under the dashboard.
Swap the relay: Identify the wiper relay, remove it, and replace it with a similar relay from another function (like headlights) to test.
Test operation: Reconnect the battery and check if the wipers function correctly.

4. Inspect and Repair Wiring

Visual inspection: Examine the wiring harness for wear, corrosion, or pinched wires.
Test connections: Use a multimeter to check for continuity in the wires leading to the wiper motor.
Repair damaged wires: Use a wiring harness repair kit to fix any identified issues.

5. Test Wiper Motor

Direct power test: Connect the wiper motor directly to the battery using jumper wires to check if it operates correctly.
Replace motor if necessary: If the motor does not respond, it may need to be replaced.
