Replace the bulb it works when you turn on the driving lights and when you brake. there are two little springs inside the light one is for the brake light and the other is for the driving light. All you need to do is replace the bulb. good luck.

You have to remove the interior trim of the lift gate.
Open the hood to the engine compartment. Take hold of the headlight light bulb connector. Push the connector in and turn it at the same time. The headlight light bulb will come out. Reverse the process to install the new light bulb.
