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 rear wiper blade on the back windshield window.

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 wiper blade size in inches is 13".

A few compatible replacement 13" wiper blades with their part numbers are as follows: Anco 31-13, Bosch 13-CA and ClearPlus 20131.

The only tool needed to remove the old wiper blade is a plastic automotive panel pry bar.

Slide Cover To The Left
Plastic Hook - Underside of Cover
Plastic Bracket - Old Wiper
The first step is to gently pry up the base of the black plastic cover on the wiper blade.

Use a plastic automotive pry bar tool to pull the base of the cover (close to where the wiper arm attaches to the window) straight away from the SUV.

It should pop out about a half inch when it is released.

Slide the black plastic cover to the left (towards the driver side) of the SUV to release the hook on the underside of the cover from the old wiper blade.

Set the plastic wiper cover aside in a safe place.

Press In Release Tab
Use Plastic Tool - Press Tab
Disconnect Old Wiper Blade
Locate the small black plastic tab at the center of the old wiper blade.

Press in the tab with your finger tip or the plastic tool to release the old wiper blade.

Slide the old wiper blade towards the right (passenger side) of the car to release it from the metal hook at the end of the wiper arm.


Towel - Protect Glass
Line Up New Wiper Blade
Slide Bracket In To Hook
Place a towel on the window to protect it from being cracked, shattered, chipped or scratched just in case the wiper arm smacks down on to the glass.

I recommend buying the Bosch 13-CA wiper blade since it has great reviews on Amazon.

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

Slide the new wiper blade to the left (driver side) of the car to secure the plastic mounting bracket in to the hook.

The new wiper blade should "click" securely in to place.

Mount Secure In Hook
Lower Wiper To Window
Hook - Underside of Cover
Double check that the new wiper blade is locked in place to the wiper arm.

Gently lower the wiper blade down to the window.

Line up the plastic hook on the underside of the wiper cover with the opening in the new wiper blade.

Slide Cover To Right
Push Down Base of Cover
New Wiper Blade Installed
Slide the plastic cover to the right to secure it in place.

Gently push the plastic cover until it firmly snaps over the base of the wiper assembly.

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