You're oversimplifying. The auto control requires several sensors that
aren't present with the manual controls.
Actually, I did this on an accord. Just bought an auto climate control, and
a temp sensor. very easy. It should be possible to do it on an elantra, with
a temp sensor too.
It seems that the auto climate control is not sold in North America.
