I can't get my back up lights to come on while I am in reverse. I put new bulbs in but they still don't work. I also checked the fuse and it appears to be good. Is there some trick or a none problem associated with these lights?

there is a relay\ switch on top of the trans......I beleave somebody will correct me if I am wrong

It is the switch 90% of the time. The location varies by year model but it is the only thing on the trans with wires on it.
