I have a 1997 Toyota 4Runner. The 15-amp "dome" fuse keeps blowing when I replace it. None of the following work: clock, radio, door/headlight chimes, dome lights, power locks, security remote. I recently jumped a dead battery and found the 100-amp alternator fuse blown. Replaced that and car starts/runs fine. Sounds to me like there's a short somewhere but would like advice on how to confirm - and correct - the problem. Thanks.
