A compressor on its way out can show up as warm air at the vents, a noisy or stiff pulley, or oily residue around the fittings. With the engine off and cool, a look over the compressor and its connections is a fair first check. Warm air can also come from low refrigerant, a leak elsewhere or an electrical fault, so have the cause found before you replace the compressor.
