ok, first your going to need to know if you have ECC (electric climate control) or not. The easiest way is to look and see if the blower moter switch has a "aut" position, if it does you have ECC, if not you have MCC.
either way you take a small screw driver and pop the temperature and air distributor knobs off, and take the knob off for the blower speed, after you take the knobs off you will see screws, take those screws out and pull gently and evenly on the face plate, and you will be able to see the bubs that unlock on the back from there, Good luck!
