Chevy Uplander (2005) Headlight bulb or turn signal replacement:

It is important to ensure all lights are working for the safety of you and others on the road.

Headlight:

In order to gain access to the head light bulbs, the headlight assembly must be removed. There no easy way to gain access to the lamps with the assembly installed. Open hood. Use 10mm wrench to remove faster on top of the light assembly closest to the rubber hood rest. You then need to remove the silver looking pin near the grill. This pin is snapped in place. Rotate counter clockwise and then pull pin straight out. The light assembly will now have to be pulled past the front header panel near the grill. Use care as the light is pulled past the grill panel. When you have this done there is one more fastener holding the light to the vehicle. On the far out side edge of the light near the fender panel, there is a ball socket fastener holding the light to the vehicle internal frame. Pull straight forward to pull the ball pin out of the socket. It will take a lot of force, but be careful as you apply force and pull light out forward. My light took some wiggling up and down, left and right until the ball released. Once the light is out, the lights are accessible. Both the normal and high beam light sockets rotate counter clockwise to remove from the headlight housing. There is a very tight detent in the counter clock rotation which took a fare amount of force. Once it "clicks" past that point during rotation, the light socket was able to be pulled from the light housing. The light bulb pulls straight out of the socket. Please use a clean towel or gloves to protect your fingers. Bulbs can sometimes crack and cut your fingers. Also, when you install the new lamps, use a towel or cloves as not to get oil on the glass which can cause uneven heating of the glass and crack it under use.

With the light assembly out, it is now easy to reach down into the vehicle to change the turn signal. This lamp is colored since the turn signal lens is clear.

Once bulbs are replaced, please test them before reassembly just in case of any issues. The headlight assembly ball socket will snap back into place easy. Once that is in, press the rest of the light back to its normal place. When the holes are lined up, please the silver colored rod back into its slots all the way down the inside of the light assembly. It then can be rotated and locked back into place. Reinstall the 10mm bolt on top of the light assembly near the rubber hood rest. Again check the lights to insure nothing is out of order.

Rear Lights:

To gain access to the bulbs to the real light assemblies, you must remove the light housings. Open up the rear hatch. Use a T30 Torex screwdriver and remove the two screws on the inside of light. Once those are out, the light assembly can be pulled out slightly from the vehicle. On the side of the van, the light assembly is held in place by two snap fasteners. Pull the light towards the rear of the vehicle to disengage the outside edge fasteners. Once done, the light assembly will be loose and the bulb sockets are accessible. They rotate counter clockwise release from the housing. The bulbs themselves pull straight out of the socket. Please use a towel to protect your hands and to make sure no oil gets on the bulb surface. Once done, reinstall the light assembly by first lining up the two plastic fasteners on the outside edge to the vehicle panel and press the light assembly to the vehicle. Reinstall the two screws and test light. Be sure to have someone press the brake for you to ensure your brake light works.
