On my 93' transport # Remove radio from car. # Remove face # unplug the "keyboards" (3 of them) # Remove the two light panels # run 5v-12v through the light boards to see which bulbs are burnt # Get new bulbs # sodier in new bulbs # reinsert the two light panels

plug in all three keyboards # attach face # reinstall radio I

really recommend testing the light panels before reassembly I put the radio back in the car twice before bench testing them. Then the third install I forgot to pug the lower keyboard back in. I haven't remove the radio a Fourth time yet to fix that. Go slow and try not to forget any step.
