remove the instrument panel cover..remove the radio...the black cover of the radio will need to be removed...you'll need a star screw set...once you have the screws undone...be care..the buttons might fly off...inside there should be really tiny bulbs...its either a 73,73, or smaller than a 26...just match em up at an auto store...then they should work.

Thanks.
