How to Troubleshoot Your Chevrolet Tracker Headlight Assembly
Your Chevrolet Tracker headlight assembly can be easily diagnosed even if you will have to do it by yourself. Here are some ways to find out what is causing the component to go bad.
Make a list of possible problem areas
Just because the assembly is bad doesn't mean that the entire thing has failed. Sometimes one function-whether it's the parking, fog, or headlights-can bring the whole component down. Check each function for continuous and sporadic use as they could have caused the wiring to go bad. Examine the headlights for condensation as well since this is a common cause for faulty headlights.
Determine the bad ground wire
Another common cause of a bad headlight assembly is that one of its ground circuits might have shorted or opened. To find the bad ground wire, remove the connector from the back of the headlight. If you see three wires in the connector, then one of them is ground; but if you see four, then two of them are ground. Trace these wires back from the connector as far as you can see them. The one or two that are connected to the chassis are the ground wires. With a multimeter, check its resistance. If the ground wire does not show continuity, then this means it is broken.
Check for a bad bulb
One likely cause of a bad headlight assembly could probably be due to a failed bulb, especially when only one headlight does not work. Just like your regular household bulb, headlight bulbs have a limited life depending on the number of hours used and how much vibration they have been subjected to. The filament inside this component will eventually burn out, usually within 600 to 2,000 hours of use. Simply replace the bad bulb with a new one.
Other troubleshooting tips
Clean the headlight assembly before moving on to do some electrical troubleshooting. Sometimes, this component can go bad just because you haven't given it proper maintenance. Make sure to remove all the grease and film, and dry the entire assembly first before reinstalling it.
Tips on Taking Care of a Chevrolet Tracker Headlight Assembly
The Chevrolet Tracker's headlight assemblies are one of the very important safety components of your vehicle. Their lights allow you to see and drive at night. Without these, you'd be playing a guessing game with the road because of your blindness. However, headlights only work great when they shine at their brightest. Any less and the difficulty dramatically increases. This shouldn't happen to you if you want to fully enjoy the features of your Chevy. Here are some things you can do to take care of your Tracker's headlight assembly:
Take care of the lenses.
Any hindrances in the form of fogs, fades, and discolorations greatly affect the intensity of the bulbs. Solid dirt also instantly blocks beams passing through. Lenses overexposed to sunlight fade as it gets old. Other than these, cracks and other forms of physical damage should be worked on as soon as possible. If cavities are left unattended, contaminants can exploit these and enter the assembly to damage it further. That's why it's important to keep the plastic lenses of the assemblies clear and stain free. This is vital in giving you bright and brilliant headlights. There are lots of products and DIY resources that can guide you on how to go about this.
Maintain the lights' aim.
The constant movement of the Tracker affect where the beams of the headlights point. What used to stay front and center can be tilted in all directions. Other than this, if the vehicle is carrying too much weight at the back, its nose ends up higher than its tail. This results to lights pointing upward rather than down on the road. Search the assembly to locate the dedicated adjustment screws for you to return the aim of the lights to the right direction.
Handle bulbs with gloves.
If you need replacement bulbs for your headlights, chances are the old ones are burnt out. Never touch and handle new ones with your bare and hands. The oil on your skin may end up on the bulb's surface. When these stained lights are installed, the light heats the oil and hastens the rate at which the bulbs burn out. Wear safety gloves to prevent this from happening.
