How do you adjust the headlights on a Chevy Trailblazer?

To adjust the headlights on a Chevy Trailblazer, you can follow these steps:
1. Open the hood and locate the vertical and horizontal adjustment screws on top of the headlight assembly.
2. The vertical adjustment screw is used to adjust the up and down movement of the headlights, while the horizontal adjustment screw is used to adjust the left and right movement.
3. Use a screwdriver or pliers to turn the adjustment screws. Turning the vertical adjustment screw clockwise will raise the beam, and turning it counterclockwise will lower the beam.
4. To adjust the headlights horizontally, turn the horizontal adjustment screw clockwise to move the beam to the right, and counterclockwise to move it to the left.
5. It’s recommended to perform the adjustment against a garage door or a wall to ensure an even line.
Remember to make small adjustments and test the headlights after each adjustment to ensure they are properly aligned. If you’re unsure about the process, it’s always a good idea to consult the vehicle’s owner’s manual or seek professional assistance.
