Interesting development today. I got bored since the rain was still drizzling down, so I went and sat in the car and started toying with the dash. I took out the right hand control pod for the heat, a/c and wipers in an effort to trouble shoot the non-working buttons. I checked for loose connections, unplugged everything and then plugged it back up...I re-installed it and, viola...the A/C works. At least a little bit. Some of the controls still don't work right, and air is cool rather than cold, but it is coming on and blowing air. That leads me to think it's simply a problem with the pod itself, which I hope to be able to remedy soon. I've got a line in to the expert on the digital dash and hope to hear some good news soon....
