GMC 9441732 High Beam Bulb

Detach the cable from the negative terminal of the battery, ensuring that the lockout feature of the Theft lock audio system is turned off if equipped. If applicable, raise the flap or remove the plastic cover over the headlight to access the bulbs. For some models, it may be necessary to remove screws or nuts and pull the headlight assembly forward; on 1997 and later Buick models, pull up the two retaining clips to release the headlight housing, while on 1997 and later Grand Prix models, remove the two mounting screws, pull the headlight housing forward, and release two clips at the back. Note that on Grand Prix models with a center light bar, both the center light bar and the side marker light must be removed to allow for headlight housing removal. Unplug the electrical connector and twist the bulb lock ring counterclockwise to remove the headlight bulb holder assembly, ensuring not to pull the bulb out of the holder as they are sold as a single unit. Installation follows the reverse order of removal.
