Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, wire brush, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check the Wiper Fuse

Locate the Fuse Box: Find the fuse box under the dashboard or in the engine compartment.
Remove Fuse: Use a fuse puller or needle-nose pliers to remove the wiper fuse.
Inspect the Fuse: Look for a blown fuse (broken filament). Replace with a fuse of the same amperage if damaged.

3. Test the Wiper Switch

Disconnect Battery: Disconnect the negative terminal of the battery for safety.
Access the Wiper Switch: Remove the steering column cover if necessary.
Perform Continuity Test: Use a multimeter to check for continuity through the switch in all positions (off, low, high, and intermittent).
Replace Switch if Faulty: If the switch is defective, disconnect and replace it with a new one.

4. Inspect Wiring and Connectors

Visual Inspection: Check for frayed wires or loose connectors in the wiper circuit.
Clean Connections: Use a wire brush to clean any corroded connections. Secure all connections properly.

5. Test the Wiper Motor

Direct Power Test: With the battery still disconnected, connect the wiper motor directly to the battery using jumper wires.
Observe Motor Operation: If the motor runs, it is functioning properly. If not, replace the wiper motor.

6. Reassemble and Test

Reconnect Battery: Reconnect the negative terminal of the battery.
Reassemble Components: Replace any covers removed and ensure all components are secured.
Test Wipers: Turn on the wiper switch to confirm proper operation.
