Electrical Check:
- Use a multimeter to check the voltage at the power steering motor. Ensure it meets the manufacturer's specifications (typically around 12V).

3. Inspect Steering Components

Remove Steering Column Covers:
- Use a socket set to remove any screws securing the steering column covers.
- Carefully detach the covers to expose wiring and components.
Check Steering Rack:
- Inspect the steering rack for any leaks or physical damage.
- If damaged, replace the steering rack according to the manufacturer’s specifications.
Inspect Steering Angle Sensor:
- Locate the steering angle sensor and ensure it is properly connected.
- If faulty, replace the sensor and recalibrate.

4. Reconnect Battery and Test
