2016 Terrain Windshield Wipers
Lift Wiper Arm Off Window
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 the front windshield window wiper blades.

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.

The OEM blade sizes in inches are as follows: Driver Side 24" and Passenger Side 17".

A few compatible wiper blades with their part numbers include the following: Rain-X 5079280-1 & Rain-X 5079283-1, Bosch 24OE & Bosch 17OE, Michelin 8524 & Michelin 8517, Trico 25-240 & Trico 25-170 and Anco C-24-OE & Anco C-17-OE.

No tools are required to change the wiper blades.

You might need a plastic pry bar tool, screwdriver, car key or some other blunt object.

Square Plastic Button
Push In Button To Release Blade
The first step is to lift the wiper arm off the windshield until it remains in the raised position by itself.

Then locate the black plastic square button located near the end of the wiper arm.

Press in the button with your finger tip or use a screwdriver, key or other similar object.

Slide Old Blade Up
Old Blade Detached
While you have the release button pushed in, carefully pull the old wiper blade up and out of the bracket at the end of the wiper arm.


Towel - Protect Glass
Line Up New Wiper Blade
Place a towel on the windshield to protect the glass from being shattered, cracked, chipped or scratched just in case the wiper arm smacks down on to the window while you are replacing the wiper blade.

I recommend buying the Rain-X 5079280-1 and Rain-X 5079283-1 wiper blades since they have excellent reviews on Amazon.

Line up the plastic mount at the center of the new wiper blade with the metal bracket at the end of the wiper arm.

Slide Wiper In To Bracket
Lower Wiper To Windshield
Slide the new wiper blade in to the end of the wiper arm until it clicks securely in to place.

Gently lower the wiper arm down to the windshield.

For the best wiper performance, I recommend thoroughly cleaning off the windshield and applying a window treatment product such as Rain-X.
