My reverse lamps quit working. Is a fuse? Where is it located? I have no book and didnt see any fuse for them.

Please..........Tell us what year Aurora you have.

Sorry. 1995.

Have you checked the bulbs themselves ? That would be my first choice. They are easy to replace too.

They both worked one day and the next they didnt. What are the odds that both bulbs blew at the same time?

I'm not sure on the 1995 but try the fuse labeled exterior lamps.
Other than that try checking all fuses that are defiantly not for the lights.
Which fuse boxes have you checked?
I think you may have four.
