Compresser is out of freon. Needs a re charge. Or compressor blown
your car ac will only blow hot air when there coolannt in the car is finished or the car is oveerheated.
You are low on coolant to the heater core.
A.C. circulates air(just like a fan) and turns it cool.
about 5 minutes
Yes it could.
Check for low coolant
Your car can only create cold air if the engine is running to make the coolant work correctly. If your car is idle, your engine is still hot but your engine isn't running so the air you are receiving is actually air heated by the engine.
Insufficient amount of coolant or thermostat not opening
Only blows cold air with the a/c on while driving, your cooling fan or fan clutch is bad depending on the year, make and model.......... Only blows cold air with the heater on while driving, you will have a bad or broken internal a/c - heater control door.....
it is drawing the hot air off the engine.
Could be the Climate Control Unit or Clogged heater core.
I would defrost it. Get a hair dryer and blow hot air on it.
