2001 Aurora Interior Lights

Have 2001 Aurora that keeps blowing 10A fuse under rear seat that's on interior lamp circuit. Checked four bulbs, two front, two back and they looked okay no shorts. As soon as fuse is installed it blows. Getting 10-12 volts across. Changed mini relays and still no help. Do not have wiring schematic so I am now lost.

I realize this was posted about 7-8 years ago, just hoping you're still a member and solved the problem. I just bought an aurora over the weekend and it's doing the same thing except it might wait a day or two before it blows the fuse.
