emergency

If it's just on one side, check the connector to the light assembly.

Do you know how I can check this?

I'm not exactly familiar with your car, but the light assemblies should have a single connector going to it so it can be removed. There might be other wires and connectors on the assembly, but there should be a main one. You may have to lift up a carpet or panel to gain access.

Did you haul anything in the car that could have pulled or crushed the wiring harness back there? While you are looking around, check for leaks that may have corroded the connection.

I hope this helps,

Thanks for your help. I haven't hauled anything major, but I think I did have some groceries in the back the day it all went out so we'll see what happens.
