Jeep Grand Cherokee Headlights
Diagnosing Faulty Jeep Grand Cherokee Headlights
The headlights are an essential part of your vehicle especially when you are driving at night or going through a tunnel. It keeps you safe especially from other passengers as they can notice you on the road. It's also a standard operating procedure to turn these on when dusk sets in; otherwise, you'll be hailed by a traffic enforcer and get reprimanded for not having them switched on. But, the Jeep Grand Cherokee headlights also experience problems that can't be avoided. Here are some troubleshooting tips to help you out if ever this part is about to fail.
Faulty and loose connections
Usually, the reason why the headlights do not work anymore is because of a busted light bulb. Check if there's a burnt bulb that might need to be replaced. Also, examine the connections, such as the connecting wires and socket, if there's a corroded bulb. Units may also have loosened, so you'd better tighten them so that the headlights can start working again.
It's inevitable for your lights to get wet especially when you are driving under the rain. If you start noticing that the headlights do not light up the road properly, it could mean that there's moisture buildup in the headlight lenses. This can affect the brightness of the headlights. You can take out the lens and wipe off the moisture using a clean rag or paper towel.
It's also quite inevitable for the headlights to start flickering. If it starts to fluctuate or dim during acceleration, you might have to check the strength of the battery's charge. This is also caused by an alternator that's about to give up. When this happens, it affects the charging of the battery, which will eventually lose its charge and give up.
If both headlights aren't functioning at all, go ahead and take a good look at the connecting wire systems. Check out the headlight relay, module, dimmer switch, headlight switch, or look out for a faulty wire. If you discover that there's a problem with the said units, have them replaced. It's much cheaper rather than having a whole new headlight installed on your ride.
