Make sure your vehicle is turned off and parked on a level surface. Disconnect the negative battery cable to prevent any electrical short circuits.

Position the new ignition switch in the same place where the old one was. Secure it with screws using the torque wrench to the recommended specifications.

7. Reconnect the Wiring Harness

Reattach the wiring harness to the new ignition switch. Make sure it clicks into place to ensure a solid connection.

8. Reassemble the Steering Column

Put the steering column covers back on and secure them with screws. Double-check that everything is assembled correctly.

I’ve noticed that my 2002 Chevy Tahoe has been hard to start lately and the dashboard lights flicker. Could this be a sign of a faulty ignition switch?

Absolutely! Difficulty starting and flickering lights are classic symptoms. Also, if your power cuts off intermittently, that could point to ignition troubles as well.

Another sign to watch for is if your accessories suddenly lose power while driving. That’s a strong indicator that your ignition switch may be on its way out.

Exactly! I experienced that last week. Almost crashed because my Tahoe just lost power!
