How to Replace a Saturn Ion Head Light

The Saturn Ion (manufactured from 2003 to 2007) uses an integrated low beam and high beam headlight per headlight assembly (drivers side and passenger side). The halogen headlight is inserted into the back of each headlight assembly and accessed through the engine compartment. While both low beam and high beam filaments rarely burn out at the same time, the headlight needs to be replaced when one or the other beams fails for optimal night vision.

Instructions

1

Park the Saturn Ion on a level ground surface, apply the parking brake, ensure the headlight switch is in the off position, and release the primary hood release latch from inside the vehicle.

2

Release the secondary hood release latch located underneath the center of the hood in front and lift the hood prop to rest the hood onto the prop.

3

Lift the two headlight assembly retaining brackets located at the back of the headlight assembly with the faulty headlight. The brackets only need to be lift up about an inch to unseat the headlight assembly retaining tabs.

4

Pull the assembly forward away from the Ion to unseat the ball socket headlight aiming guide pins.

5

Place towel under the assembly while resting it on the front bumper to avoid scratching the paint on the bumper.

6

Angle the headlight assembly outward far enough to reach behind it and disconnect the wire harness plugged into the headlight socket. Lift upward on the harness plug tabs and then pull it out of the headlight socket.

7

Turn the headlight retaining ring 1/3 of a turn counterclockwise and then extract the headlight and ring from the back of the headlight assembly. Discard the spent headlight.

8

Put on a pair of latex gloves before handling the replacement bulb. If skin accidentally contacts the glass bulb section of the composite headlight, a heat or weak spot will occur and shorten the life of the headlight.

9

Insert the replacement bulb through the center of the retaining ring and then align the tabs of the ring and headlight to the grooves in the headlight assembly. Turn the ring and socket 1/3 of a turn clockwise to tighten and secure the headlight in place.

10

Reconnect the wire harness plug to the socket of the headlight and test the headlight for proper operation before replacing the headlight assembly and retaining brackets.
