C-5 6 speed reverse lights not working

Any suggestions on what/how to troubleshoot my reverse lights not working? Car has 16K miles, never seen rain. I'm thinking it's not physically making contact to activate the switch......
Thanks, J.J.

If not its probably the wiring or the relay. The relay is in the box under the hood, I don't recall which one. If that relay is good (they RARELY go bad) then it is the wiring which is the worst part.

At this point I brought it to vette doctors who pulled the tranny tunnel plate to run a new wire. The $100 was well worth not having to do that on my back in the driveway.

My car has gone through three or 4 switches. Go under the car and pull the plug off the switch and jump the terminal with a piece of wire. With the key on, the lights should come on. If its a bad switch, you can get it at the dealer. Takes a few minutes to replace.

Hey 65GGvert,

You wouldn't happen to have a similiar drawing for an A4? I think I need to replace my switch too. Thanks!

I can't find a picture or description of the backup switch for the A4. My feeling is that it is in the shifter area, but I can't find it in the service manual.
