I just got my coolant flushed and i still have no heat. My pcv valve moves back and forth with the tempature changing but I only get warm air. Even at 85 the air is still cold (not ac cold). Please help has anyone had this problem?

 

pcv valve? you mean the heater control valve? sometimes they get stuck... and sometimes the little vaccum switch on it goes bad.

 

I don't think it is stuck because it is moving. The AC works and when the fans are off heat is still being given off but when I turn the fans on high cold air comes out.

 

Your thermostat could be bad, or your heater core is clogged. I'll look in my manual and see what it says to check.
