There is a second one I believe. It is near the center of the dash in between the glove box and the radio, somewhere in that area. It is concealed by the duct work. Take the bottom duct work off and look up under there and you'll see it. It's near or on the end of the main heater box, for lack of a better way of describing it. If I remember correctly, that is the one that controls the defroster. At least it was on mine. If I can find a schematic, I'll post it for you. HTH
