Car Aircon Blowing Hot Air, then cold? Check This Before Replacing AC Compressor or Adding More Gas

Is your car AC blowing hot air, or does your car AC blow cold then warm after driving for a few minutes? In this video, I’ll show you how to diagnose the problem step by step before you replace the compressor, add more refrigerant, or waste money on the wrong part. If your car AC stops blowing cold after a while, it does not always mean the AC compressor is bad. The problem could be low refrigerant, a refrigerant leak, a bad AC pressure switch, a weak compressor clutch, a faulty AC relay, a cooling fan problem, a clogged condenser, a dirty cabin air filter, a freezing evaporator, or a blend door actuator issue inside the dashboard. This video explains why your car AC blows cold then warm, why your car AC blowing warm air can happen even when the system works at first, and how to separate a real refrigerant problem from an airflow problem or temperature-control problem. Many drivers search for how to fix car AC not blowing cold air, but the correct fix depends on what the AC is doing when it changes from cold air to warm air. You will learn what to check when your car AC blowing hot air but Freon is full, what it means when the compressor clutch turns on and off quickly, why the AC may work while driving but blow warm air at idle, and why a bad condenser fan can make your car air conditioning blowing out hot air even when the compressor is still trying to work. We’ll also cover the most common causes of car aircon blowing hot air then cold, including low refrigerant pressure, high AC pressure, dirty condenser fins, poor airflow through the evaporator, a clogged cabin air filter, evaporator freezing, bad AC relay, bad pressure sensor, compressor clutch gap problems, and a blend door that mixes hot air with cold air. If you are asking: Why is my car AC blowing warm air? Why is my car AC blowing hot air? Why does my car AC stop blowing cold air after a while? How do I fix AC in car blowing hot air?

In this video, you’ll learn how to check the compressor clutch, cabin air filter, condenser fan, condenser blockage, refrigerant level, AC pressure switch, AC relay, compressor clutch gap, evaporator freezing, AC drain, cold AC lines, and blend door actuator. You’ll also learn the difference between weak airflow and warm airflow, because those two problems can feel similar from the driver’s seat but usually point to different causes. Before you add more refrigerant, replace the compressor, or assume your AC system is finished, watch this full diagnostic guide. A simple fan problem, dirty filter, bad relay, pressure switch issue, or blend door fault can make your car AC blowing hot air problem look much worse than it really is.
