I replaced mine cause half of that cluster wasn't on. theres 2 bulbs in there. one for the front 3 buttons and one for the rear 3... I got 10 bulbs on ebay. I can try and dig up the exact ones but they were 95mA 12v mini bulbs. I first went to radio shack but theres were only 30mA and very dim. ok... this can be done fairly easily. first you gotta get the bulbs. look for ones that have solid wire leads. theyre easier to work with. pull the cluster out and disconnect the harness. take it inside to the table. theres a few screws that hold it together from the backside. take those out and pay attention that theres one a little longer on. its the center one I think. set the trim piece aside. youll see how the cluster snaps together. use a flathead and unsnap the plastic clips on one side. once you start taking the thing apart, make sure you keep it upside down... pull the top half off keeping the switches face down in the palm of your hand. theres a circuit board in there and you can see the bulbs at each end. pull the board out. at this point, lay the rest down with the switches on the table. youll see a rubber mat in there once you pull out the board. if you pull that up a tiny bit, theres pins going to each switch. you push the switch, it pushes a pin into the rubber mat that pushes a button on the board. I dropped that and after finding all the pins, I had to put them all back in the right spots. anyway... youll have to take the blue condoms off the bulbs and save them. then unscrew the bulbs. 1/2 or 1/4 turn will allow you to pull them out. youre gonna reuse the bases. see how each lead is wound around either side of the base. unwind them and the old bulb will pull out. put the new bulbs in slipping the leads through the 2 tiny holes in the center of the base. once the bulb is all the way in the base, you can wind the leads like the old ones were. I went around twice. this is where the solid wire leads make it easier. once that's done, put the blue condoms back on the bulbs and screw the bulb back into the board. make sure the wire leads are making contact with their metal strips on the board and you should be good. put it all back together and you should have light again. I replaced both bulbs just to make sure the cluster was all the same color and brightness.... hope this helps.
