The reset switch should be behind plastic on the interior side panels in the back end. If you open the tailgate looking into the car, on the left or right side, there should be a plastic cover (part of sidewall) that removes (kinda back near tail-lights). The switch is usually hidden behind one of these access panels. Can also check if you have a floor storage in there.
