Not sure what is involved with the replacement of the parts on my car. I read the service paperwork, and it says "System had no charge in it,evacuate system pressure would rise slowly indicating a leak. Added dye to system and .5 lbs. of refrigerent, ran for 15 min. checked with black light has hole in CONDENSER "
Very poor diagnostic procedure, IMO. You really should replace the dryer, too, or you could be looking at replacing the compressor prematurely too.. Let me explain a bit. When diagnosing A/C systems, it is prudent to tickle a Schrader valve to see if any pressure exists. If there is any pressure, then an A/C machine or gauge set should be attached to see what is going on. If there is an undetectable small leak, causing diminsihed performance, them recovery, evacuation, recharge and dye installation is a good procedure. In the case of the Honda, a quick blip of a Schrader valve would have revealed no pressure at all. Next step would be to pressure test the system with an inert gas (nitrogen is a favorite), and the leak would have been easily found. Total diagnostic time - 2 minutes. Leak detection using the vacuum method is archaic, and only finds the big leaks that could have been found quicker (IE cheaper for the customer) by pressure checking. If there is a MAJOR leak (such as in this case), I always recommend replacing the dryer/accumulator. There is no doubt that it is sucking up moisture from the hole. Moisture is public enemy #1 for an A/C compressor, and failure to replace the dryer in a case like this COULD lead to premature compressor failure. Moisture is such a problem that many aftermarket A/C companies will not warranty their compressors (new or reman) if the dryer wasn't replaced at the same time. Consider yourself warned..
