Removing the seat only takes a few seconds. Begin with the seat bottom by pressing it towards the back of the car to separate the seat-frame's wire from the clips in the car's floor.

The seatback is next. Usually there are two bolts, accessible once the bottom is taken off, that hold the back in place. The bolts were missing on our car, so the back simply lifted out.

Using a 3/8-inch drive ratchet, detach the two nuts holding the motor in place.

We also disconnected some of the clips holding the hydraulic lines in place, allowing the lines to move more freely when removing the motor.

Unplug the motor from the car's wiring harness.

With the nuts taken off and the motor unplugged, the motor is lifted out of the car.

It's a good idea to have some sort of container handy when removing the lines because some hydraulic fluid will spill out. Using a line wrench, carefully loosen and detach the fittings as shown. At this point, the motor is completely free from the car.

Installation of the new motor is simple. Reinstall the line fittings on the new motor, set the it back in place over the studs, and plug the it into the car's wiring harness. When installing the bolts, place the motor's black ground wire onto the driver-side mounting stud, as shown here.

While tightening this nut, use a screwdriver to keep the ground wire centered. Complete the installation by reinstalling the hydraulic-line clips and the back seat.
