    There are three screws that hold down the assembly. Two of the screws are on top, the third on is on the bottom. Once you remove the screws, pull the assembly straight out and disconnect the electrical connector. You should have access to all the bulbs now. Once replaced, connect connector and slide the assembly back into place, lining up the screw holes.
