Hi guys. Here's an easy way to check the neutral safety switch. Turn the ignition switch on. You can leave the transmission in park. Unplug the switch at the front left corner of the transmission. There are three wires in a straight row. Connect the two outer wires with a stretched-out paper clip or cotter pin. Watch closely. If you see a tiny spark when you move the paper clip around, you know current is flowing and it has to be going to the backup bulbs. If you need further proof, run in back and look at the lights. They will be on. A defective switch is somewhat common and is a very inexpensive repair.
