Solution

1. Preparation

Gather necessary tools and parts for the repair.
Disconnect the negative terminal of the battery to ensure safety.
Allow the vehicle to cool if it has been running.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add OEM-approved fluid if low.
Inspect the fluid for contamination; if contaminated, proceed to replace it.

3. Inspect and Repair Wiring

Examine the wiring harness connected to the power steering motor for any signs of wear or damage.
Repair or replace any damaged wires or connectors.
Ensure all connections are secure.

4. Replace Power Steering Motor (if necessary)

Remove any components obstructing access to the power steering motor.
Disconnect the electrical connector from the motor.
Remove the mounting bolts securing the motor to the steering column.
Install the new power steering motor in reverse order of removal, ensuring it is torqued to manufacturer specifications.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for error codes; clear any stored codes.
Test the steering assist functionality by turning the steering wheel at various speeds.
