I guess i got my answer . I wanted to change mine too. Very disapointed.Probably not. The LTZ has the automatic climate control system, which includes at least one, but most likely several sensors in the interior of the car to determine whether to use heat or AC and which vents to use, not to mention fan speed. The same question has popped up from time to time about various GM vehicles in other forums, and the few that have actually researched the changes needed have found it to be far to complex and expensive to bother with.
