Are you tired of your car headlights randomly turning off while driving? It can be frustrating and dangerous to suddenly lose visibility on the road. Luckily, there’s a simple fix for this issue that you can do yourself. In this article, we will guide you through the troubleshooting process step by step, so you can fix your low beams and ensure a safer driving experience.

Step 1: Identifying the Problem

When your low beams turn off randomly, it’s important to determine the cause of the issue. In many cases, the problem lies with the headlight driver module, specifically the HDM solid state relay. To check if this is the culprit, start by inspecting your fuse box located in the engine compartment of your car. Look for number 46, which corresponds to the HDM relay.

Step 2: Replacing the HDM Relay

Once you have located the HDM relay, remove it from the fuse box. In most cases, the HDM relay can be easily replaced with a new one. We recommend using the AC Delco relay, which is known for its reliability. You can purchase this relay from your local auto parts store or online. Make sure to match the part number (AC Delco 15016745) when purchasing a replacement.

Step 3: Installation

After acquiring the new relay, you can now install it in the fuse box. Simply insert the relay into the appropriate slot and ensure it is securely in place. Now, it’s time to see if the replacement fixed the issue. Turn on your headlights and observe if they stay on without any random shutdowns.

Step 4: Testing

While the replacement of the HDM relay should solve the problem, it’s always a good idea to perform some additional tests to ensure everything is working correctly. You can follow a more in-depth diagnostic process by watching a video tutorial by a YouTuber named Mayo 3lt, who provides detailed instructions on testing the prongs for continuity and voltage.

Conclusion

With a new HDM relay in place, your low beams should no longer turn off randomly while driving. This easy troubleshooting guide will help you fix the issue and ensure a safer and more reliable driving experience. Remember to always prioritize safety on the road, and if you encounter any further issues with your headlights or electrical system, consult a professional mechanic for assistance. Drive safely and enjoy the road with fully functioning low beams!
