How to Troubleshoot Tesla Model 3 Headlights Won’t Turn On

Step 1: Check the Headlight Switch

The first thing you should do is check the headlight switch to make sure it is turned on. The headlight switch is located on the left side of the steering column. It is a small, round switch with three positions: Off, Park, and Headlights.

To check the headlight switch, turn the key to the On position and then press the headlight switch to the Park position. The headlights should come on. If the headlights do not come on, then the headlight switch is likely the problem. You can try cleaning the headlight switch with a dry cloth to see if that fixes the problem. If cleaning the headlight switch does not fix the problem, then you will need to replace the headlight switch.

Step 2: Check the Headlight Fuse

The next thing you should do is check the headlight fuse. The headlight fuse is located in the fuse box under the hood of the car. The fuse box is a black box with a red cover. It is located on the driver’s side of the engine compartment.

To check the headlight fuse, open the fuse box and find the fuse labeled Headlights. The headlight fuse is a 20-amp fuse. Remove the headlight fuse and inspect it for damage. If the fuse is blown, then you will need to replace it with a new fuse. You can buy headlight fuses at most auto parts stores.

Step 3: Check the Headlight Wiring

If the headlight switch and the headlight fuse are both good, then the problem is likely with the headlight wiring. The headlight wiring runs from the headlight switch to the headlights. It is a black wire with a yellow stripe.

To check the headlight wiring, you will need to remove the headlight assembly. The headlight assembly is located on the front of the car. It is held in place by two bolts. Remove the two bolts and then carefully remove the headlight assembly.

Once you have removed the headlight assembly, you can inspect the headlight wiring for damage. Look for loose wires, damaged wires, or corroded wires. If you find any damage to the headlight wiring, then you will need to repair or replace the damaged wiring.

Step 4: Check the Headlights

If you have checked the headlight switch, the headlight fuse, and the headlight wiring and you still cannot find the problem, then the problem is likely with the headlights themselves. The headlights are located on the front of the car. They are held in place by two bolts. Remove the two bolts and then carefully remove the headlights.

Once you have removed the headlights, you can inspect them for damage. Look for cracks in the lens, burned-out bulbs, or damaged reflectors. If you find any damage to the headlights, then you will need to repair or replace the headlights.

Conclusion

These are the steps on how to troubleshoot Tesla Model 3 headlights won’t turn on. If you have followed these steps and you still cannot fix the problem, then you will need to take your car to a Tesla service center.
