Look on the left rear corner of the transmission to see if there's a three-wire connector. If there is, that is the neutral safety switch and backup light switch. By 2006 they changed the circuit to a stupidly complicated computer switching circuit. I don't know which year that started.
If you have that plug, turn on the ignition switch, disconnect that plug, and use a stretched-out cotter pin or paper clip, or even a needle nose pliers to connect the two outer terminals in the plug. If you look closely when you do that and you see a tiny spark, that means current is flowing and the backup lights are on. If you can't see that spark, you or a helper will have to look if the lights turned on. If they do, that proves the entire rest of the circuit is okay and you need to replace the switch.
