The fuse is most likely with all the others, under the cover to the side of the heater controls, that is unless they radically changed them between 87 and 94.
Some of the fuses protect several low currect circults, so I expect there is one fuse that protects the radio, mirror dimming etc.
Check in the owners manual, it should tell you which fuse protects what and what the fuse should be rated at.
