The reverse lights are not working I found out. There's no power to the trunk wiring on that circuit only. The fuse is ok and is getting power. I have to assume the neutral safety switch is the culprit, then. It is a C4 with floor shift, original. The shop manual says that the reverse light actuater is integral with the neutral safety switch in the automatic floor shifters. Am I missing something or is it time for a new switch assembly? Is this going to be a hard to get part if it is needed? I'd really like to get this car inspected soon.
I have the same problem with mine. The neutral safety works but no backup lights. Let me know if you figure it out...
