Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shock.
Ensure the work area is clean and well-lit.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the power steering and remove it.
Check the fuse for continuity using a multimeter.
If the fuse is blown, replace it with one of the same amperage.

3. Check Wiring and Connections

Visually inspect the wiring harness connected to the electric power steering motor for any frayed wires or corrosion.
Disconnect the connector and clean the terminals with electrical contact cleaner.
Reconnect the harness securely.

4. Voltage Testing

Reconnect the battery and turn the ignition on without starting the engine.
Use a multimeter to check for voltage at the power steering motor connector while someone turns the steering wheel.
If voltage is absent, trace back to the power steering control module for further inspection.

5. Replace Electric Power Steering Motor (if necessary)

If all tests indicate a faulty motor, remove the steering column cover.
Disconnect the wiring harness from the electric power steering motor.
Unbolt the motor from its mounting location.
Install the new motor and reconnect the wiring harness.
Replace the steering column cover.
