2001 Saturn SL1 Dash, tail and DRL lightd do not work

The tail, dash, DRL lights and the chime that sounds when your lights are on and you open the door all quit working. I found that a 10 amp fuse in the under hood fuse block labeled Park LP was blown. A replacment also blew. I determined that the brown power wire was shorted to ground when the light switch was turned on. I disconnected all tail, side marker and front parking lights to no avail it was still shorted. I also disconnected the dash panel wiring, still shorted. Based on some posts on the internet I began to think it might be caused by the BCM. I tried finding the BCM (behind the glove box or so I was told) I removed part of the dash and glove box but could not find the BCM. The next day I tested for the short again and there was none. I replaced the fuse and everything worked fine. I put all the dash and glove box back together and everything still works fine. My question is do you think this could be a BCM problem or just a shorted wire that got moved some how. Thanks
