Hi. The switch for turning on and off the lights in the aft cabin is located inside the tailgate lock. I´ve never tried it but I was told that it is possible to replace the switch without having to bye a complete lock assy. Your problem could lie here.
Best regards

Had the same problem on my 1988 300TE. Tried to solve it today. Got the tailgate lock out and located the two micro switches. Tried different things without luck. Put the lock back in and wanted to remove the bulbs from the four lamps. When doing this I had the tail gate open but the lock closed. (just push on the hook but don´t get your fingers in the way) When I took out one of the lights on the "D" frame, the light went out! After some investigation I found that the ground/earth connection on the light came in contact with the frame when installed. The connection on the light assy is not isolated and will eventually make connection to ground, and therefore light up all four bulbs in the aft cabin. I put some tape on the connections as isolation and the problem went away. Check all lights and do the same on them. Hope you can cure your problem in this way.
