The boy finally got his 92 300E up to our 3rd generation MB indie yesterday, and the response was less than positive.
As I expected, they said fixing the AC would cost more than he paid for the car, and therefore wasn't worth it. They say that the compressor is seized, which is why the clutch won't engage. I'm not sure I buy this, as I can turn the compressor by hand, but the clutch does not engage with power applied to it, so I'm still convinced the clutch itself is bad. So now we're on to Plan B, with the assistance (hopefully) of this august group. I may have access to a vacuum pump and an R134a manifold gauge set. More on that in a minute. My thought is to replace the compressor, flush the system, put a new (rebuilt?) compressor and drier on it and recharge with either an R12 equivalent or change over to R134a. My questions revolve around the process and materials used to flush the system, something I have never done, and the use of an alternative refrigerant in an effort to keep the efficiency of R12, since this climate is really tough on 124 systems converted to R134a. Also, rebuilt or new when it comes to a compressor? I'm checking with my former neighbor who is a commercial AC guy. I am pretty sure he has a vacuum pump but not sure about the manifold gauge set. Can you get a HF set that does both R12 and R134a?
