Okay. If the front works, the rear should as well because they all get power from the same relay. So, if this happened all at once, I suspect there is a broken wire (open).
If you look below, I attached the wiring schematic for the exterior lighting. Note that there are two pages that I cut in half to make them readable. Additionally, I highlighted the wiring related to the parking lamps
In the first two pics, the park lamp relay and front lamps are shown. The last two pics show the rear lights. All have the same red wire with a blue tracer. I need you to locate that wire in the tail lamp assembly and using a test lamp or multimeter, see if there is power present on either side of the vehicle. Have the headlamps on when you check.
Let me know what you find,
See pics below.
