Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical system.

2. Inspect and Repair Ignition Switch

Remove the steering column covers using a screwdriver or socket set.
Locate the ignition switch and disconnect the wiring harness.
Test the ignition switch with a multimeter to ensure it is functioning correctly.
If faulty, replace the ignition switch with a new one, reconnect the wiring, and reassemble the steering column covers.

3. Check Steering Column Lock Mechanism

With the steering column exposed, visually inspect the lock mechanism for any obstructions or signs of damage.
If binding is present, lubricate the lock mechanism with a suitable lubricant to ensure smooth operation.
If the mechanism is damaged, replace it with a new part.

4. Power Steering Check

Inspect the power steering fluid reservoir; if low, top off with the recommended fluid type (usually ATF or specific power steering fluid).
Check for leaks in the power steering lines and connections; replace any damaged components.

5. Reassemble and Test

Reattach all components and covers that were removed.
Reconnect the battery and ensure all electrical connections are secure.

6. Final Test

Start the vehicle and test the steering operation at various speeds and conditions.
Ensure the steering column functions correctly without locking up.
