What do I do?

I have a 95 Mustang,it's my baby. When I put the car in reverse the fuse blows every time. Why does this happen? and what do I do?

You may have a defective light bulb or socket for the back-up lights. Try removing both light bulbs, replace the fuse and see if it blows again, with no bulbs in place. If it does not blow, install two brand-new bulbs and see if the fuse blows.
If it still blows, a bulb socket may be defective.
