Automatic climate control requires air/temp sensors such as in the air ducts, the headliner, (I think even one behind the front grill) etc. I believe the BCM would have to be reprogrammed as well. Even if you wanted to use it as a "manual" control it still wouldn't work since the wiring harness is different (I think 3 out of 4 of the plugs are the same but one uses a blue where the other is black).
