Why is my Subaru WRX AC blowing hot air?

Possible Causes of Subaru WRX AC Blowing Hot Air
There can be several reasons why your Subaru WRX AC is blowing hot air. Here are some possible causes based on the search results:
1. Low or overcharged refrigerant: One common cause of AC blowing hot air in Subaru WRX is low or overcharged refrigerant. This can be due to leaks or improper maintenance.
2. Compressor malfunction: A malfunctioning compressor can also cause the AC to blow hot air. Issues with the compressor can include electrical problems or mechanical failure.
3. Dirty condenser or evaporator coils: Over time, dirt, grime, and other particles can accumulate on the condenser and evaporator coils, hindering their ability to release heat and cool the air. Cleaning these coils may help resolve the issue.
4. Faulty blend door actuator: The blend door actuator controls the flow of hot and cold air into the cabin. If it malfunctions, it may prevent the AC from blowing cold air.
5. Defective evaporator temperature sensor: The evaporator temperature sensor helps regulate the temperature of the AC system. If it is defective, it may cause the AC to blow hot air.
6. Bad AC pressure sensor: The AC pressure sensor monitors the pressure in the AC system. If it is faulty, it may not accurately regulate the cooling process, resulting in hot air blowing from the vents.
7. Electrical issues: Electrical problems, such as blown fuses or relays, can also cause the AC to malfunction.
It’s important to note that these are just possible causes, and a proper diagnosis by expert technicians is recommended to accurately identify and resolve the issue with your Subaru WRX AC.
