Raise Wiper Arm Off Window

This automotive maintenance tutorial was specifically written to assist owners of the second generation (2010, 2011, 2012, 2013, 2014, 2015 & 2016) GM Buick LaCrosse sedan in changing the front windshield window wiper blades.

Owners of other General Motors vehicles such as the Chevrolet Impala, Monte Carlo, Malibu, Spark, Sonic, Cruze, Volt, SS, Camaro, Caprice, Corvette, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado, Buick Verano, Regal, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra, Terrain, Acadia, Yukon, Savana, Cadillac CT6, ATS-V, ATS, ELR, CTS, XTS, XT5, SRX, Escalade and Holden Commodore may also find these DIY instructions to be helpful.

The OEM wiper blade sizes in inches are as follows: Driver Side 26" and Passenger Side 18".

The only tool needed to remove the old blades and install the new ones is a flathead screwdriver or a plastic pry bar tool.


A few compatible replacement wiper blades with their part numbers are as follows: Bosch 26A & Bosch 18A, Michelin 8526 & Michelin 8518, Rain-X 5079281-1 & Rain-X 5079275-1, Anco 31-26 & Anco 31-18, Champion CH-26-H & Champion CH-18-H, Valeo 900261B & Valeo 900181B, Trico 25-260 & Trico 25-180 and Aero AERO-J2618 (26" & 18").

Gently Pry Open Locking Tab

Flip Up Lock Tab
The first step is to lift the wiper arm off the windshield until it remains in the raised position by itself.

Use either a flathead screwdriver or a plastic pry bar tool to gently pull out the rectangular shaped black plastic locking tab near the middle of the old wiper blade.

Flip open the lock tab until it is perpendicular with the wiper arm.

Rotate Old Blade Perpendicular
Push the old wiper blade down to disengage the mounting bracket from the hook at the end of the metal wiper arm.

Rotate the old wiper blade away from the wiper arm until it is almost perpendicular (90 degree angle) to the wiper arm.

Pass Hook Through Opening

Towel - Protect Glass
Pass the metal hook at the end of the wiper arm through the opening in the old wiper blade.

I recommend buying the Bosch 26A and Bosch 18A wiper blades since they have excellent reviews on Amazon.

Place a towel on the windshield to protect the glass from the being cracked, shattered, chipped or scratched just in case the wiper arm smacks down on to the window while you are replacing the wiper blade.

Line up the new wiper blade with the metal wiper arm.

The rubber blade should be pointing forward and away from the windshield.

Pass the metal hook at the end of the wiper arm through the opening in the new wiper blade.

Lower Wiper To Windshield
Firmly snap in the plastic locking tab to secure the new wiper blade in place.

Double check that the new wiper blade is firmly attached to the wiper arm.

Gently lower the wiper arm down to the windshield.

For the best wiper performance, thoroughly clean off the windshield and apply a glass treatment product that will repel water such as Rain-X.
