How to Change a Side Headlamp Directional Bulb on a 2002 GMC Envoy
- 1). Raise the hood of the Envoy and prop it open. Locate the two retaining tabs at the top of the light assembly. Lift the retaining tabs with a flat-head screwdriver.
- 2). Slide the headlight assembly forward until you can access the wiring harnesses behind the bulbs. Detach the wiring harness connections from the three bulbs and remove the assembly from the truck.
- 3). Twist the turn-signal bulb counterclockwise and pull it straight back to remove it. The turn-signal bulb is the bulb on the outside edge of the assembly. Insert the new bulb and turn it clockwise.
- 4). Reconnect the wiring harnesses on each of the bulbs and replace the assembly in the front of the truck. Push down on the retaining clips to secure the headlight assembly in place.
- 5). Repeat the process on the opposite headlamp if needed.
