As of now nothing on the inside of my 87 monte carlo works. The radio, the overhead lights, the dash lights, the lighter, and the rear defroster button all don't work. The only thing that runs is the heat/A/C. I have already replaced the fuses and check all the fuse plgs to make sure they are getting power to them so I was wondering if anyone knew whta my problem might be?

 

that sounds like an expensive problem :\ do cars that old have a BCM? because all of those things would be controled now a days through it. hmm.
