Solution

1. Preparation

• Gather required 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 and Replace Power Steering Fuse

• Locate the fuse box, typically found under the dashboard or in the engine compartment.
• Remove the fuse for the power steering system using a fuse puller.
• Inspect the fuse for continuity; replace if blown.
• Reinstall the fuse and reconnect the battery terminal.

3. Replace Power Steering Motor (if necessary)

• Remove the plastic covers to access the power steering motor.
• Disconnect the electrical connector and any mounting bolts.
• Carefully remove the motor from its housing.
• Install the new electric power steering motor by reversing the removal steps.
• Torque mounting bolts to manufacturer specifications.

4. Check Rack and Pinion Assembly

• Inspect the steering rack for leaks and damage.
• Replace any damaged components, including seals or the entire rack if necessary.
• Reconnect all lines and ensure they are properly torqued.

5. Final Assembly and Testing

• Reattach any covers or panels removed during the repair.
• Reconnect the battery terminal.
• Start the vehicle and check for any warning lights.
• Test the steering function to ensure proper operation.
