Yup, my thread was deleted because I was posting competitors to fastlane for a servo rebuild.
From what Colin told me over the phone, I interpreted it as the guy doing electrical tests of the CCU itself, and the de-ice or perhaps defrost was causing the system to go nuts.
Perhaps he thinks the climate control is fried, and $600.00 retail for a rebuild sounds about right. Of course, you can find good ones for less than half that price.
I was hoping to get the part number so we know exactly what they're talking about.
Soon to be good used Servo for sale in the parts section...
Oh well, it was a good thing to replace anyway.
