My problem is the same, but with a different car. After doing a little research, evidently one should check the fuse for the lights, and if that isn't it, then check a switch on the side of the transmission with some wires going to it. Sorry I don't know more. Good luck.
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.

For a 2003 Jeep Grand Cherokee, the fuse for the backup lights is typically a 15-amp fuse located in the fuse box under the hood. Always refer to the owner’s manual or the fuse box cover for the exact location and specifications, as they can vary slightly by model and configuration. If the backup lights are not functioning, check this fuse first, along with the bulbs and wiring.
if it is a jeep Cherokee it needs a neutral safety switch mounted on the passenger side of the transmission. if it is a jeep grand Cherokee it needs the backup switch located on the drvers side of the transmission
brake relay or sensor
Check the ground wire connection.
Just replaced the headlight bulbs in a 98 Grand Cherokee that had the same problem. It had the wrong bulbs in it. It had 9007's in it. Calls for 9004's.
It could be a fuse or yes a short.
the reverse switch in the transmission
If parking and dash lights work: Maybe bad bulbs (double filamented) Bad socket? Bad ground circuit?
intermitten problems are the worst to figure out i would first start by changing the bulbs then i would change the wiring harness. i know i had a car that when the tail lights were on the blinkers wouldn't work and it turned out to be a short in the harness.
Check the backup light switch.
