To change the headlight bulbs, you will need to remove the wheel liner cover to gain access to the back of the headlamp assemblies. Then you can pull off the screw cap / cover that seals the bulb into the headlamp assembly for the bulb you want to change. Once the cap is off, you will need to disconnect the harness from the back of the bulb. With the harness off, you will then need to either twist a black lock ring to release the bulb, or you will need to push on a metal lever to release the bulb (this varies on models and high and low beams).
Install in the reverse order....

The headlamps should be held in by two large pull clips . Pull up on them and the headlamps should slide out.

You should be able to get to it by removing the headlight

1. Remove the headlamp fasteners.
2. Using a pry bar, gently pry in the center area of the headlamp assembly. Pry the headlamp assembly straight forward in order to unsnap the headlamp ball stud from the ball stud socket.
3. Slide the headlamp straight forward and disconnect the headlamp electrical connectors from the forward lamp wiring harness.
4. Remove the headlamp from the vehicle.
