Are you sure it has a heater valve? If there is a heater valve on the 9-5 it is indeed going backward. The c900 has a heater control valve. It is a mechanical device to regulate coolant flow into the heater core actuated by control inside the cabin. Any c900 owner knows the heater control valve is notorious for leaks. SAAB recognized this and changed the design in the 9000. The 9000 colant circuit for heating the cabin has no valves or any mechanical device to regulate coolant flow. Instead the heater core is enclosed in a box. Cabin temperature control is done by regulating air flow throught the box. Although the heater core still goes bad and leak the robustness of the design improves significantly over that on the c900. Maybe someone can clarify if indeed the 9-5 has this feature. I rather doubt it.
