2016 Acadia Dome Lights
Gently Pry Out Housing
Two Metal Spring Hooks
This automotive maintenance tutorial was specifically written to assist owners of the first generation (2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 & 2016) GMC Acadia in changing a burnt out dome light bulb (A.K.A. the rear passenger courtesy reading light bulbs).

Owners of other General Motors vehicles such as the Buick Verano, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra 1500, Terrain, Yukon, Denali, Savana, Spark, Sonic, Cruze, Malibu, Impala, Volt, Camaro, Corvette, SS, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado and Express may also find these DIY instructions to be helpful.

The replacement bulb is part number 168 or W5W. A few other miniature wedge base bulbs include the 158, 2825, 194 or a compatible LED bulb.

The tools needed to complete this procedure include a flathead screwdriver or a plastic automotive panel pry bar tool and a Torx T-10 star bit screwdriver.

Light Housing Removed
Release Power Plug
Loosen Counterclockwise
Insert a plastic automotive panel pry bar tool in between the light housing and the headliner.

Alternatively, you could use a large flathead screwdriver covered with a thin micro fiber cloth to prevent from scratching the plastic surfaces.

Gently pry down the light housing to release the metal spring clips and the two metal friction fasteners.

Do not pry at the front edge (closest to the windshield) since there four black plastic hooks that secure that side in place.

Pull the light housing out of the headliner and press the release tab on the electrical connector before sliding the plug straight out of its socket.

2nd Torx T-10 Screw
Remove 3rd Screw
3 Screws Removed
Remove the three screws that secure the black plastic light bulb housing from the tan plastic lens cover by turning them counterclockwise with the Torx T10 star bit screwdriver.

Set the three screws aside in a safe place.

Lift Off Light Housing
Push Old Bulb Out of Socket
Old Bulb Removed
Lift the black plastic light housing off the tan plastic lens cover panel.

The easiest way to remove the old light bulb is to push it out from the back.

Old # 168 Light Bulb
Push In New # 168 Bulb
Replace Light Housing
Push  a new # 168 bulb straight in to the socket.

If necessary, you may also use any other miniature wedge base bulbs such as the # W5W, 2825, 158, 194 or a compatible LED unit.

Lower the black plastic light housing on to the lens cover panel.

Tighten 3 Screws
Turn T-10 Clockwise
Push In Power Plug

Try to avoid over tightening the screws to prevent from cracking the plastic light housing.

Push the electrical connector straight in to its socket.
