Why does the system take the heat I paid so dearly for and reject it from the cabin when defrost mode is selected? Defrost mode burns up an incredible amount of range when it is on because of this. I can see why it was done. To cut costs and make it the same way your ice driven cars, where an installation like this makes sense. But it is wrong in this case. You need to either port the refrigerant to another condenser in side the car that just recirculates cabin air through both the condenser and the evaporator, just like a dehumidifier does, or duct the air from the existing condenser to accomplish the same thing.. of course it is routed the conventional way on hot days for air conditioning.
