The Tucson is a crossover vehicle that offers excellent value for money, but there are times when this vehicle may malfunction.  Specifically, your headlight might not be working as they should be. In this case, you can get some assistance from this article to fix your headlights or other problems that may occur on your Hyundai Tucson.

Check the fuse

The first thing you should do is check the fuse. If the fuse has blown, then this will likely cause your headlights to not work. When you are reading your owner’s manual, you need to find out how your particular vehicle functions, but when a fuse blows, it is relatively simple to replace the fuse in most circumstances.

It is very important that you replace the old fuse with a new fuse that has the same rating and same amount of amps. If the fuse blows again shortly after you replace it, you likely have a circuit problem somewhere else in your circuit.

Look for any debris in the headlight unit

The next thing you should do is look for any debris in your headlight unit. If there is anything inside of it, then this could be causing your headlights to not work properly.

This could be a rock or other small object that may have gotten into the headlight unit and may be causing it to not work properly. You can remove any objects that are blocking the headlight unit by using a small brush or similar device.

Check the wiring

The next thing you should do is check whether there is any damage to the wiring of your headlights. If there is any damage, then this could be causing them to not work properly and needs to be fixed immediately so that they can work again as they should.

You can use a multimeter to test for potential problems with your wiring if you are unsure about whether it has been damaged or not.

Replace the bulbs

When these headlights age and experience some wear and tear, they often lose a little bit of their brightness. Sometimes just simply replacing the bulbs can solve the problem.

The headlight lenses could also be the issue. Headlight lenses may discolor or oxidize after a certain period of time. If the headlight lenses are dirty, it is time for you to clean the assembly. If your headlights become foggy, it may be because there is condensation on the inside of the lenses. Sometimes foggy headlights mean that you must fix or replace your headlight assembly.

Replace the headlight unit

If there is no damage to the wiring of your headlights, then you should check whether there is any damage to your headlight unit itself. If there is any damage, then this could be causing your headlights to not work properly and therefore needs to be fixed immediately.
