On mine, it has an electronic water valve and must be installed a particular way for it to work. Have you checked this? As I recall, you have to program the system by jumpering a white wire to a ground which then caused all the actuators and motors to self-learn. Just a thought because the Chevelle only runs 155-160 degrees down the road in this cold weather but still blows nice and warm through the vent. I can't imagine the thermostat would have you running so cold that you get no heat, but I suppose it is a cheap part to swap out and see.
