No. Antifreeze is added to the engine cooling system to help the engine run cooler and keep the water from freezing in the winter. A refrigerant (also called freon) is what makes the a/c blow cold air.
No! Thermostat.
Check Antifreeze level..make sure there are no leaks under the vehicle.
heater core possibly plugged and leaking
Probably - your head gasket is blown. Antifreeze will be coming out of the tail (exhaust) pipe.
Check your antifreeze or cooling level this happened to me.
Probably need to add antifreeze. Check the Radiator not the overflow tank. If you are low on antifreeze it will not circulate through the heater core.
heat core. leak. thermostat. no antifreeze.
It doesn't really blow it out it just warms the cold air.
If it does blow just not cold air you should see if it needs to be recharged
An air conditioner blows out heat
why does ac blow warm air? why does ac blow warm air?
No, not if it's on a heat setting. Most home thermostats have a "Fan" setting that will blow cold air if the attic is cold.
