Fuse #8 keeps blowing...

[Fox89GT]

I have a dead short somewhere on circuit #8. Fuse panel say:

courtesy lights...>pulled all bulbs
clock...> don't have one
key warning...> how do you check that?
radio...> took it out
fuel filler door...> how do you check that?
power mirrors...> took out switch

Did anyone every have this problem before on #8? How do I check the key warning and fuel door for a short? Any other ideas to try? This is not a major problem but a enough of a drag not to have these things working.
