Your car might be a facelift but it doesn't always mean you'll have the facelift heater controls, especially with the EJ. As elchunk stated the prefacelift heater controls use sliders attached to cables. It is quite a big swap but can be done if you have the right parts. Prety sure the dash would need to come out to gain access to most of what is needed. Have seen it in someones build guide, so should come up if you have a search through the forum.
