Its a whole lot more involved than just swapping out the control module. The auto climate controls use several sensors that the manual climate controls dont. Also the blower motor is controlled using resistors with the manual controls and the auto controls uses a blower motor control module.

So you are saying that it is a PITA and not worth doing?
