i have an 03 s with the standard heat/ac controls. i have found a used electronic climate control and would like to swap it with the one i have. what else do i need to complete this swap? do i only need to swap the in dash control units? thanks.

 

did you ever figure this out, i just came across your post...i'd like to do the same. except i have an 02 MC so i wanted to see if i could use an 03 or earlier model...

 

I think you'll find it's a big job. I don't remember specifics, but I read on here somewhere that the entire system is different and you'd need the vent motors and stuff.
