92 Fleetwood Rear Doors NO POWER

My 92 fleetwood has no power (seemingly) to the rear doors. Power windows, locks, lights, cig. lighters are all dead. Not a fuse problem, not a relay problem. Windows, locks, etc all work when bypassed with 12v. Everything else works, front locks, windows, etc... Help

It is a 1992 Cadillac Fleetwood 4.9 FWD.

Thanks so much!
