Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and a torque wrench.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the vehicle battery to prevent electrical shock.

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse using the fuse diagram.
Remove the fuse using a fuse puller or flathead screwdriver.
Inspect the fuse; if it’s blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the wipers.

3. Test and Replace the Wiper Motor

If the fuse is intact, proceed to the wiper motor.
Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for power at the motor connector while activating the wiper switch; if no power, the issue may lie in the switch or wiring.
If power is present, connect the wiper motor directly to the battery to see if it operates. If it does not, replace the wiper motor.
Remove the motor by unbolting it and disconnecting any attached linkage.
Install the new motor by reversing the removal steps, ensuring all connections are secure.

4. Inspect and Repair Wiring

If the wiper motor is functional, inspect the wiring harness for any signs of wear, fraying, or disconnection.
Repair any damaged wires by splicing in new wire sections and using heat-shrink tubing for insulation.
Check connectors for corrosion and clean them if necessary.

5. Test the Wiper Relay

Locate the wiper relay in the fuse box or under the dashboard.
Remove the relay and test it using a multimeter or replace it with a known good relay.
Reinstall the relay and check if the wipers operate normally.
