How to replace the headlight assembly or headlight bulb or cornering, sidemarker, park, or turn signal bulb on GMC Canyon?

The first step for bulb replacement is to turn the headlamp switch to OFF and move the ignition switch to LOCK. Use a wrench to disconnect the headlamp from its installation and exterior grille. Twist the daytime running lamp or turn signal bulb 1/4 turn in the opposite direction to take it out from its position. Then remove the electrical connector from the low beam headlamp or high beam headlamp. Connect the electrical connector to the new bulb before pushing and turning the daytime running lamp , high beam headlamp , low beam headlamp , or turn signal bulb a quarter clockwise until it locks. Reinstall the bolts holding the headlamp and secure them at 10 N.m (89 in lb). End with a complete check of headlamp function and put back the front grille. You should treat new halogen bulbs with care by keeping them away from skin and water plus wearing protective eye gear.

How to Safely Replace a Headlight and Headlight Bulb (HID) on GMC Yukon?

Replacing either the headlamp assembly or headlamp bulb (HID) requires you to extract the front grille followed by removing headlamp retainer pins and then drawing out the headlamp assembly in order to disconnect the electrical connector. Access to the headlamp bulbs becomes possible by first removing the rubber cups. Begin by installing the new bulbs before putting on the rubber cups for installation. The electrical connector ties to the lamp assembly first while replacing the lamp assembly back to its position in the vehicle by using headlamp assembly retainer pins before securing the front grille. Be vigilant about the high voltage and current operations of the high intensity discharge system since opening the ballast or arc tube assembly or probing between electrical connectors causes severe shocks and burns. Maintain safe distances between the arc tube and the headlamp housing as well as bulb shield when uninstalling or installing to prevent any damage from occurring.
