Dave. As soon as my new/used one comes in I'll contact you. Do you have a way to test the unit itself? I'm reasonably certain the one I bought will be good but if the CC doesn't work after I install it I'll need to figure out where to go from there. As an aside, what can a person do with a vacuum block (behind the glove box that routes vacuum to the climate control doors) that has apparently gone bad after only 9 months? Is there a fix or where can I buy one at a reasonable price? Thanks for your time. Chuck.
