I have two or three ccu's I have pulled from some junkers and each one does the same thing, no change. The ccu's work in other cars just fine. I am leaning toward the change-over valves located behind the ccu. I have vacuum going all the way to them but no vacuum going to the vacuum pods.

I have wondered about the AC compressor clutch. I plan to take her to the repair shop tomorrow. I have owned this car for almost three years with no problems whatsoever (except replacing alternator). This will be the first "real" money I will have spent on it. Fives years ago I would have dived right into this thing but I ain't as interested in these old cars like I used to be. It's just a way to travel for now. She's a really nice car, not a rag, so I want to get another 100,000 out of her at least but I want everything to work right while I do. Wouldn't be surprised if I trade it for an older w123 chasis.

Thanks!

Kevin
