This automotive maintenance tutorial was specifically written to assist owners of the third generation (2014, 2015, 2016, 2017, 2018 and perhaps also the 2019 and 2020 model years) Toyota Highlander SUV 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 Toyota, Lexus and Scion vehicles such as the 4Runner, Avalon, 86, C-HR, Camry, Corolla, iM, Land Cruiser, Mirai, Prius, RAV4, Sequoia, Sienna, Tacoma, Tundra, Yaris, FR-S, xB,  xD, tC, xA, CT 200h, ES 250, ES 300, ES 330, ES 350, IS 250, IS 350, RX 300, GS 250, NX 300 and RX 350.

The tools needed to remove the interior door panels include a plastic pry bar tool, a small flathead screwdriver and a standard Phillips head screwdriver.

The OEM door speakers can be removed with either a Phillips head screwdriver or a 10mm socket with a 1/4" drive ratchet.

Then move to the door opener handle and door lock rocker switch area.

Use a small flathead screwdriver to gently pry out the plastic trim piece located behind the door opener handle.

Set the plastic trim cover aside in a safe place.

Then use the plastic pry bar tool to carefully lift up the rear of the switch panel.

There is also a friction fastener at the front of the switch that will need to be loosened with the plastic pry bar tool.

Re-Insert Ball Into Socket
The OEM front door speakers can be replaced with aftermarket car speakers in the following sizes: 6 1/2" (6.5"), 6 3/4" (6.75") and 6"x9".

I highly recommend applying some Dynamat sound deadener to the metal door frame and the back side of the plastic door panel to help stop vibrations and rattles when you crank up the volume. The sound deadener will allow your new speakers to sound their best.

To replace the plastic interior door panel, hold it near the frame and tilt away the top edge.

Lower the ball at the end of the door opener handle cable (green plastic collar) into its socket closer to the bottom of the assembly.
