what is evaporative emission system vent valve
I have an 2007 Chevy Impala with the 3.5L engine. I have no heat at all. The car will get to operating temp and not overheat. Both radiator hoses are hot and squishy and both heater hoses are hot and stiff. I’m at a loss
Having a no heat situation can be a serious issue in the winter months. You have done well so far in your diagnosing. You have eliminated almost all of the heating system. The coolant is getting up to temperature and flowing through the heater core as it should. If you are hearing the heater blower motor coming on then all you are left with is the ventilation system. This system has an actuator that control the air temperature door. I would suspect the actuator to be at fault.
No heat in car but air is blowing
