Warm air from the vents or a grinding or squealing noise can mean the compressor is worn, though low refrigerant or a leak can show up the same way. With the engine off, look over the belt and check for oily residue around the compressor and fittings first. If the compressor itself is the cause, this one replaces it, as other Four Seasons remanufactured A/C compressors do.
