Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. There are a few common cause on your vehicle that will cause this. Start by checking the negative ground connections at the negative battery cable. Make sure that where they connect to the body and engine are clean and tight. If they are then you more than likely have a failing body control module or ignition switch. The ignition switch is the most common failure that causes this. It can be hard to diagnose this without a scan tool that reads body control module data. I hope this helps. Let me know if you need further assistance.
