The rear windshield wiper motor is one of those things that always seems to fail just when you need it the most, in the rain, usually at night as well. Replacing the motor is pretty easy and should only take about an hour.

Replacing the motor requires removing the trim pieces from the inside of the rear hatch. Be sure to have a set plastic pry bars or trim removal tools. These are usually just pieces of flat, strong plastic that really help out when trying to pop a trim piece off the car.

Begin by opening the rear hatch and locate the center trim piece (green arrow).

Now carefully pry back the arms (green arrows) holding the electrical connector to the motor.

When re-installing the trim panels, check that the metal clips (green arrow) line up with the slits in the rear hatch (yellow arrow).
