How do you test for a bad ignition switch on a 2008 Saturn Vue?

To test for a bad ignition switch on a 2008 Saturn Vue, start by checking for any electrical issues, such as blown fuses or poor connections. You can then use a multimeter to measure voltage at the ignition switch terminals while turning the key; if there's no voltage when the key is in the "on" position, the switch may be faulty. Additionally, observe dashboard lights when turning the key—if they don't illuminate, it could indicate a bad ignition switch. If these tests suggest a malfunction, consider replacing the ignition switch.
