no heat in system
If the engine is not warming up to operating temp. then the thermostat would need to be replaced. IF it is warming up to operating temp. there is a heater water pump, heater valve, and blend door actuator which any could be bad.
I need a diagram on how my hoses an where they come from that go to my heater valve
