Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Check the fluid level; if low, top up with the manufacturer-recommended fluid.
Inspect the fluid for contamination or burnt smell; replace if necessary.

3. Test Electrical Connections

Reconnect the battery terminal.
Use a multimeter to check the voltage at the power steering motor connector.
- Expected voltage: approximately 12V with the ignition on.
- If voltage is low, check wiring for damage or corrosion.

4. Replace Power Steering Motor (if necessary)

Disconnect electrical connectors from the power steering motor.
Remove the mounting bolts securing the motor to the steering assembly.
Install the new power steering motor by reversing the removal process.
Torque specifications: typically around 25-30 ft-lbs (verify in repair manual).

5. Reassemble and Fill

Reconnect all electrical connectors and ensure they are secure.
Refill power steering fluid to the appropriate level if it was replaced.
Bleed the power steering system by turning the steering wheel from lock to lock several times.
