My 92 Cadillac El Dorado had a stereo installed, and since, I've lost power seats, door locks, trunk realease and mirrors. I've checked every fuse I know of, under the hood in the fuse block, and the one in the trunk. All hot fuses are good. Is there a hidden fusable link or something that I'm missing??!!?? PLEASE HELP!
