The front expansion valve is clogged.
alve, check vacum line first (on heater valve)
if youre trying to turn the heater on and cold air comes out, then its most likely the heater core
Low Coolant? Bad thermostat? Heater core plugged or restricted? Heater core airbound? Heater control cable not working?
Your heater will blow cold air only.
It doesn't really blow it out it just warms the cold air.
Check Antifreeze level..make sure there are no leaks under the vehicle.
you need to replace your heater core
it wont blow heat itll blow cold air
you are low on coolingliquid !
Either a faulty thermostat or you have a low coolant level.
heater core possibly plugged and leaking
