Your heat is controlled by a flat motor that is right above your transmission hump on the passenger side. They control your heat with the blending door. Three screws hold it in. There is a plastic gear that strips in them. The NAPA # is 655-1546 if you have maual temp set. I assume you replaced the core because you weren't getting heat?
