Why is my ac not blowing cold air wen compressor kicks on and freon

Hello, You likely have a bad temperature blend door, which is inside the HVAC central housing behind the dashboard. When they fail, they are stuck on the last setting, or they reset to their home setting. The blend door has an actuator, so it may have failed as well. Lastly, the control module for the air conditioner may have failed as well. You will likely need an expert to diagnose the issue, but don't forget to check all of your fuses before you take it in for diagnosis and repair.
