The air conditioner fully froze, causing the belt to break.
Hi there. When a compressor fails, it is common for it to freeze. A compressor can break internally causing it to seize or the clutch and bearing can fail locking up the pulley. The engine will continue to turn the belt over the seized pulley until it finally wears it out and breaks it. Replacing a compressor is a large job that requires replacing other components with it, like the orifice tube, drier, and depending on the vehicle, a condenser. Flushing the lines is also necessary if the failure was internal. If you need further assistance, I recommend you have a certified technician, like one from YourMechanic, inspect the AC’s operation and suggest an appropriate repair.
