Avoiding Accidents: Troubleshooting Your Chevrolet Monte Carlo Headlight Assembly
Your Chevrolet Monte Carlo headlight assembly is not built to last forever. No matter how tough and heavy-duty the assembly is, it is still susceptible to damage caused by a number of factors, such as age, weather elements, and driving conditions. Over time, your Chevy's headlight assembly may wear out and fail to function properly. In worst cases, it may not even work at all, leaving you with absolutely no source of illumination. Defective headlights, as you very well know by now, can increase your risk of getting into a serious car accident. To ensure your safety and that of your passengers, it is important to address headlight assembly problems right away. If your headlights are malfunctioning, do some troubleshooting to save them from total failure. Read the guide below to find the causes behind some headlight assembly problems.
Headlights are designed to produce the same light intensity over the course of their service life. If your headlights are producing weaker or dimmer than normal beams, then you may have some problems with your Chevy's charging system. This may also cause the brightness or light intensity of your headlights to change when the engine is revved. If this happens, check your car's alternator system. A faulty alternator or a loose alternator drive belt is probably causing this problem and hampering your battery's ability to power your electrical components properly. To test the charging system for proper function, observe the charging voltage while your engine is on idle mode. A properly working charging system should have a voltage reading of at least 13.5 to 14.5 volts. A reading less than 13 volts indicates a faulty charging system. Have it checked by a mechanic and replace the malfunctioning parts right away.
No headlight voltage
If both of your headlights are not working, then it is most likely a voltage problem. To determine the cause, check the headlight's wiring, relay, module, switches, and fuse. These parts work together to supply power to your headlights, so you need to test each of them for damage and replace the busted components if necessary.
