Cooled (or air conditioned) seats work by confining cooled air directly in the seat where the passenger is seated. Multiple fans are put within the seat to provide air circulation. The air from the fans blows through a diffusion layer to spread the cool air throughout the seating material, cooling the whole surface.
Remove the bottom of the rear seat by simply pulling up on the front of it. Once loose, pull it up and toward the front of the car to gain access to the bottom side. Disconnect the wires for the heated seats, the sensor for the side curtain airbag, and the rear seat side airbag (if so equipped).
