I have a 95 v-6 mustang convertable. The turn signals stopped working.....the radio, the top wouldn't go down, no a/c. When I change the fuse, it works for a little while and then blows again. Sometimes I swear I smell a funky burning smell. The airbag alternately comes on. Whats up with this? Is there a short? I have no money to get it looked at, what should i check, or tell dad to check

I need some help, what could it be?
