I am the new owner of a used 87 300D i am fixing up for my wife.
Hopefully after this weekend the AC will be running.
However, I have read several ominous posts already about the Cars air conditioning system which dismay me. One was about the evaporator being suspect and a 20 hour replacement job. But I see the evaporator sitting right there in the driver side wheel well. The other was the AC system's complex electrical relays.
Is the Cars A.C. system really that complicated? Why would they make it that way? What should I be ready for this weekend? I have resurrected 5 or 6 pre 1985 import AC systems and to me the problem usually was found either in the Compressor or Hi Side Hose.
I still believe that any compressor circa 1980, especially on the W123, series usually has worn seals. I am happy to hear that the W124 300D 's compressor, even though 1987, does not have this problem.
With only average AC experience, is there a 60% chance my AC will run this weekend? Here in HUMID South Jersey cars require AC before diesel to move. Or is more probable that this weekend will be just a fact finding mission....
