have they ever worked?

Have they ever worked since you owned the car?
If you can get a wiring diagram you'll find the rear is controlled through the driver door module (DDM). It may be helpful to access the DDM with a scan tool capable of communicating with body modules. In the meanwhile, check for rain water intrusion at the switch connectors.
