The air is blowing semi-cold.
Hello. If the air is only somewhat cold then most of the time this is caused by low refrigerant. It can be a weak AC compressor, which is common on this car. I would typically start by checking the pressure in the system with a manifold gauge set. If it is low then I would just add some refrigerant and see if it blows cold. If the pressure remains low then the compressor may be failing and will need to be replaced.
