How to Troubleshoot Headlight Issues
There are several common issues that can arise with the 2012 Chevy Malibu’s headlights. Here are some troubleshooting steps you can take to determine the problem:
Check the Bulbs
The first thing to check is the bulbs. Sometimes, a headlight may stop working because the bulb has burnt out. It’s essential to check the headlights’ bulbs first, as they are the easiest component to replace.
Check the Fuses
If the headlight bulbs are fine, the next thing to check is the fuses. The headlight system has two fuses – one for the high beams and one for the low beams. If either of these fuses blows, the corresponding headlights will not work.
Check the Wiring
If the bulbs and fuses are fine, the next step is to check the wiring. The wiring diagram we’ve provided earlier in this article is an excellent reference for checking the connections between various components. Make sure all the connections are tight and secure. Any loose or damaged wires should be repaired or replaced.
Check the Body Control Module (BCM)
If none of the above steps solve the issue, the problem may be with the BCM. The BCM controls the power supply to the headlight system and can be responsible for issues such as flickering or intermittent headlights. If you suspect an issue with the BCM, take your vehicle to a qualified mechanic for diagnosis.

The 2012 Chevy Malibu headlight wiring diagram is a critical component for troubleshooting headlight issues. By following the steps outlined in this article, you can diagnose and fix any problems with your vehicle’s headlights. Remember to always refer to the wiring diagram when troubleshooting electrical issues and seek professional help if you’re unsure about any repairs.
