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 taking off the plastic interior door panels in order to upgrade the OEM speakers, add soundproofing material, fix a faulty electrical switch or replace a broken power window motor.

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 tools needed to complete this procedure include a small flathead screwdriver, a 7mm socket, a 1/4" drive ratcheting wrench, a Torx T20 star bit screwdriver and either a large flathead screwdriver or a plastic automotive panel pry bar tool.

The first two steps are to open the door and lower the power window all the way down.

Then gently pry out the plastic trim piece located behind the chrome silver door opener handle with a small flathead screwdriver or a pry bar tool.

Set the plastic trim piece aside in a safe place.

Next, pry out the rubber cover at the bottom of the door pull well in the armrest.

Remove the screw behind the door opener handle by turning it counterclockwise with a 7mm socket and a 1/4" drive ratcheting wrench.

Firmly pull out the bottom edge of the door panel to disengage the plastic pop rivets.

Continue pulling out the pop rivets all along the bottom edge and both sides of the door panel.

Push In Grey Connector
Remove the single 7mm screw that holds the OEM door speaker in place by turning it counterclockwise.

I recommend buying new speakers from Amazon since you can verify which speakers will fit your vehicle and also whether or not you will need an adapter mounting bracket.

To help reduce road noise and allow your new speakers to sound their best, apply some Dynamat Sound Deadener material to the metal door frame. It will stop vibrations and rattles when you crank up the volume.

To replace the plastic door panel, hold it near the metal door frame and tilt the top edge towards yourself.

Push in the grey plastic electrical connector straight in to its socket.
