How to Replace the High Beam Lights in a 2003 S 10

Chevy used a composite, one-piece headlamp housing system on the 2003 S-10 models. The headlamp housing contains the high-beam, low-beam and turn signal bulbs in individual compartments within the housing assembly. The high-beam bulb is a single-filament, halogen bulb with no reflector coating on the tip that snaps into the innermost compartment in the headlamp assembly. Bulb changes can be made quickly, without the use of tools.

Instructions

Removal

    1

    Park the truck, turn off the ignition and the headlights, and raise the hood.

    2

    Locate the two black headlamp housing retaining clips inside the engine compartment just above and behind the headlamp housing. Push down and in on the headlamp housing lens slightly to relieve the pressure on the retaining clips. Pull the retaining clips up to remove them from the housing. Lift the housing up and out to remove it from the grille area.

    3

    Lift up slightly on the electrical connector clip and pull the connector off the back of the innermost bulb. Use caution to avoid breaking the electrical connector clip. Grasp the high-beam bulb assembly and rotate it counterclockwise until it disengages from the headlamp housing.

Installation

    4

    Insert the bulb into the headlamp housing and rotate it clockwise until it snaps into place. Plug the electrical connector onto the high-beam bulb.

    5

    Hold the headlamps and turn signal wires in front of the two alignment tangs on the bottom of the headlamp housing. Guide the tangs into the holes in the front of the body and push the headlamp housing down and into the recess in the grille.

    6

    Insert the two retainer clips into their slots inside the engine compartment and push them fully into position.
