Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts during repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the power steering fuse using a fuse puller.
Inspect the fuse for continuity using a multimeter; replace if necessary with the same amperage.

3. Check and Clean Connections

Inspect the power steering motor connector and battery connections for corrosion or loose wires.
Clean any corrosion with an electrical cleaner and ensure all connections are tight.

4. Replace Power Steering Motor (if necessary)

Remove the lower cover of the steering column to access the power steering motor.
Disconnect the wiring harness and the mounting bolts securing the motor.
Carefully pull the motor out and install the new motor in reverse order. Torque the mounting bolts to the manufacturer's specifications (typically around 10-15 ft-lbs).

5. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Start the vehicle and check for any warning lights on the dashboard.
Test the steering to ensure the power steering is functioning properly.
