First you need to know what type of engine it is.
its an expansion valve and it is located in the black box ( in the rear unit)
Only if it is allowing Fluid to escape. Does the radiator and heater core have enough fluid to circulate. If not you will not have heat.
A blockage in the heater core is the most likely cause. This is a difficult and expensive repair.
