Fuse #8 (interior lights) keeps blowing.

[ChrisR]

I just reinstalled my moonroof shade. I realized that my keyless entry didn't work, and neither does my stereo or my interior lights. Every time I try to put a fuse in there it blows. What's the deal? I didn't change anything or mess with anything except the moonroof cover thingy. Anyone know what might be causing this?

And please don't say my stereo. I just FINALLY got that fully installed and working.
