2001 Plymouth neon reverse lights not working
You seem to have a sticky problem. Usually, lights have three problem areas, fuses, bulbs and switches, in that order. If you've changed the switch, make sure the switch is set correctly. Do this by putting the car in reverse, then measuring the contacts on the switch with an ohm meter. You can get one of those very cheaply from an auto parts store or Radio Shack.
If you have contact across the switch with the car in reverse (and the ignition switched on of course), your problem could be a dirty or blown fuse, but I assume you've checked the most obvious by now. If you have no connection across the switch, you may have to simply adjust the switch by screwing it in a little further (or out, depending on the mechanics of the switch).
If this does not solve it, the final problem area will then be wiring.
First, check (using your new multimeter) for 12 volts on one of the wires at the switch. No voltage? trace the problem from the fuse to the switch. You have votage? - the problem is on the wiring to the reverse lights.
Connect the two wires together at the switch (yes, make a dead short between the two wires) and then check the lights.
You might live in a high corrosion area - lots of acid rain - then the problem could be the earth connection, usually the body of the lamps are corroded and need to be cleaned, or else the contacts need to be cleaned. Just a small piece of 500 to 1000 water paper will do fine.
A final but absolutely most unlikely problem is that the actuator inside the gearbox is either loose or broken. Go there only with utmost caution and lots of chutzpah, a very, very, very last option.
