2015 Yaris Rear Wiper
Open Plastic Base Cover
This automotive maintenance tutorial was specifically written to assist owners of the third generation 2012, 2013, 2014, 2015 and 2016 Toyota Yaris hatchback in changing the rear wiper blade on the back windshield window.

Owners of other Toyota, Lexus or Scion vehicles such as the Corolla, Matrix, Prius, Camry, RAV4, Sienna, Tacoma, Tundra, FJ Cruiser, Venza, Highlander, Avalon, Sequoia, Land Cruiser, IS 250, ES 350, GS 350, tC, xB, xD, iQ and FR-S may also find these DIY instructions to be helpful.

The OEM 12" wiper blade is part number Toyota 85242-42030.

A few other compatible 12 inch wiper blades with their part numbers are as follows: Trico 12-A, Michelin 9512, ANCO AR-12A, Bosch H307, Valeo R12E, ACDelco 8-212A and Denso 160-5512.

No tools are needed to remove and change the rear wiper blade.

Base Cap Opened
Raise Wiper Arm
The first step is to gently swing open the hinged cover on the base of the wiper arm.

Then lift the rear wiper arm off the back window until it remains in the raised position by itself.

Rotate Away Old Wiper Blade
Blade Perpendicular To Arm
Rotate the old wiper blade away from the wiper arm.

Continue rotating the old wiper blade until it is almost parallel with the wiper arm.

Separate Blade & Wiper Arm
"C" Shaped Socket
Pop the mounting bar in the center of the old wiper blade out of the "C" shaped socket at the end of the wiper arm.


Mounting Bar - New Blade
Line Up Bar & "C" Socket
Line up the mounting bar in the center of the new wiper blade with the "C" shaped socket at the end of the wiper arm. The rubber blade should be pointing out away from the car.

I recommend buying the Trico 12-A rear wiper blade since it has excellent reviews on Amazon.

If you prefer to have the OEM blade, the part number is Toyota 85242-42030.

Insert Bar In To Socket
Pop Bar In To Socket
Insert the mounting bar in to the socket with the wiper blade almost perpendicular to the wiper arm.

Rotate the new wiper blade towards the wiper arm until the bar snaps in to the socket.

Rotate Blade Parallel
Lower Blade To Window
Continue rotating the new wiper blade until it is parallel with the wiper arm.

Gently lower the wiper arm down to the rear window.

Snap Closed Base Cap
Rear Wiper Blade Replaced
Swing the hinged cover closed and snap it back in place over the base of the wiper arm.

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