Just replaced the unit with a working eBay version which originated in a 2008 4.8i car, but which realoem says is equivalent.




I fired it up and exact same behavior. Works fine except the fan speed doesn't change (except when you hit defrost and it goes to full blast). Everything else still works.



Got a couple of good buttons out of the unit but still need to fix the problem or the wife is going to make me sell it.. any other ideas???
