Chevrolet Trailblazer aircon not cold? Diagnosis: Black oil or “Black death” What is "Black Death"? "Black Death," as it is known by A/C system service professionals, results from a catastrophic breakdown of the refrigerant-lubricant which in turn causes excessive wear inside the compressor. In a typical case of "Black Death," metal particles are circulated throughout the system contaminating other components and necessitating either thorough flushing or complete replacement. Recognizing the problem in several ways: • Your compressor may be functional, but extremely noisy during operation. • In turning the compressor clutch, you may feel "hard" spots. • The compressor may be totally frozen or locked up. • Signs of contamination may be present at the orifice tube and/or the inlet and outlet ports when the hose manifold is removed. Solving the problem. Depending on the severity of the damage and the extent of the contamination, some "Black Death" problems can be repaired by flushing the A/C system with solvents. Segments of the system are cleansed individually. Either process, flushing or filtering, can be very time consuming and expensive. At the minimum, a new compressor must be installed following this procedure. Frequently, other components also require replacement. From a cost and performance viewpoint, many A/C system technicians find that replacement of all contaminated components is the best approach. Solution: General aircon Cleaning with leak detection.
