Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, flathead screwdriver, Phillips screwdriver, and a test light.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the fuse for the wipers using a fuse puller or needle-nose pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage rating.
Reconnect the battery terminal and test the wipers.

3. Test and Replace the Wiper Motor

If the wipers still do not work, locate the wiper motor, typically under the cowl panel at the base of the windshield.
Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for voltage at the motor connector while the wiper switch is activated; if there is no voltage, there may be an issue with the switch or wiring.
If voltage is present but the motor does not operate, replace the wiper motor.
- Remove the mounting bolts securing the motor.
- Disconnect the motor from the linkage and remove it from the vehicle.
- Install the new motor in reverse order, ensuring all connections are tight.

4. Check and Repair Wiring

If the wiper motor did not need replacement, inspect the wiring harness for any signs of wear or corrosion.
Repair any damaged wires by soldering and using heat-shrink tubing or electrical tape.
Clean any corroded connectors with electrical cleaner and reconnect them securely.

5. Test Wiper Functionality

Reconnect the battery terminal.
Turn on the ignition and test the wipers at all speed settings to ensure proper operation.
