2016 Terrain Dome Lights
Insert Flathead Screwdriver
Gently Pry Off Lens Cover
This automotive maintenance tutorial was specifically written to assist owners of the first generation (2010, 2011, 2012, 2013, 2014, 2015 & 2016) GMC Terrain in changing a burnt out overhead dome light (A.K.A. rear passenger reading light) bulbs in the headliner housing.

Owners of other General Motors vehicles such as the Buick Verano, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra 1500, Acadia, 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.

A replacement light bulb is part number 2825 or W5W from various manufacturers such as Sylvania, GE, PIAA and Eiko.

You can also use any other miniature wedge base bulbs such as the # 168, 158, 194 or a compatible LED unit.

The only tool needed to access and replace the bulbs is a small flathead screwdriver or a plastic pry bar tool used to pry out the lens cover.

Lens Cover Removed
Old Bulb Exposed
Pull Out Old Light Bulb
To prevent from scratching the plastic surfaces, you may want to cover the tip of your screwdriver with a thin micro fiber cloth.

Insert the blade of the small flathead screwdriver in to one of the two notches on the rear edge of the lens cover.

Gently pry out the lens cover and set it aside in a safe place.

You might need to re-insert the screwdriver in to the other notch and pry again to release the cover.

Try to avoid using excessive force. The lens cover should pop out relatively easily.

If the old bulb was recently turned on, be careful when you remove it since it might still be hot enough to burn your fingers.

Pull the old bulb straight out of the socket.

If you have trouble gripping the old bulb, try putting on a latex or Nitrile rubber glove for extra grip.

Empty Bulb Socket
Push In New 2825 Bulb
Line Up Lens Cover
Push a new number 2825 bulb straight in to the socket.

If necessary, you can also use any other miniature wedge base bulbs such as the # 168, 158, 194 or a compatible LED unit.

Snap Lens Cover In Place
Lens Cover Replaced
Test New Light Bulbs
Line up the lens cover over the housing and gently pop it back in to place.

Test the new light bulbs by pressing the "On/Off" buttons.
