Check the 1993 Park Avenue fuses first. Check the light dimmer switch to make sure that it is functioning. If these are ok, look for a bad wiring connection.
Check the backup light switch.
Check bulbs and switch
check the ground for the lights
I would check the wires just behind the light. I had the same problem and the wires were broken a little just wiggle them as the lights are on.

Try the dimmer switch, and or, check that your body has a good ground to the frame, and battery.
Check the fuse box, you might have a blown fuse. Also it's a good idea to check the bulbs. There is one more popular problem, the cable which brings the current to the lights gets damaged sometimes. You need to check the cable for broken wires and short currents.
check reverse light switch on transmission.
If the fuse is working, then check the bulbs.
