2. Inspect and Replace Power Steering Fluid

Sub-steps:
- Locate the power steering reservoir.
- Remove the cap and check the fluid level; add manufacturer-recommended power steering fluid if low.
- If the fluid is contaminated, proceed to flush the system.
Tools Required: Funnel, power steering fluid.

3. Check Electrical Connections

Sub-steps:
- Visually inspect the wiring harness connected to the power steering control unit.
- Clean any corrosion from connectors using electrical contact cleaner.
- Reconnect any loose connections securely.
Tools Required: Wire brush, electrical contact cleaner.

4. Test and Replace Power Steering Motor

Sub-steps:
- Use a multimeter to check the voltage at the power steering motor connector while the ignition is on.
