Can a seized AC compressor?
The most common symptom of a compressor failure (besides no cooling) is a seized compressor. A restriction inside the A/C system also can starve the compressor for oil. Oil circulates with the refrigerant, so if the orifice tube or expansion valve is blocked it may cause the compressor to run dry and seize.
