Nice work. What was the problem in the CCU? Just a bad connection somewhere? Let us know how everything turns out for you.

As a side note, I finally located and ordered the Klima/Kickdown relay for my car today, should be here by week's end. I am hoping that once I install it I will see al the strange problems I have had off and off disappear. The AC obviously wasn't working, but even when it was I was also experiencing: (1) evaporator freezing up, (2) defrost not really doing any defrosting (even though I changed out the cabin air filters), and (3) every so often a bouncing tach needle. I'm pretty sure with all the electrical connections that all of these problems could be related - recall that my Klima relay (because someone had installed it upside-down) was full of water and all rusted out! Anyway, I'll let you know how it goes. Good luck!
