If it’s only the right rear that’s not working, then I would suspect that the plug or wires leading to it are the problem.

Is it bulb type? Or led plug and play unit?. Could also be the contacts in the bulb socket if lts bulb. Or did someone rewire for a different than stock set up? ( the old wire spaghetti kind)I replace my tail lights with led units that use the same plug as stock. Just mount and plug in. Or could well be something else wrong.
