Did you get the right one? There's two options.. Manual and Digital HVAC. the only difference between new and old should be wire color as a lot of the aftermarket ones use wires of all the same color for the connector.

Bring the old one to the store with you and match it up. I have the manual controls and the one I got plugged right in.
