WARNING: This page is about a different car, the 1996 Mercedes-Benz E320 and 1996 Mercedes-Benz E300. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect rear dome light harness connector. Turn front dome light switch to rear dome light on position. Measure voltage between rear dome light harness connector terminals. If battery voltage exists, replace rear dome light bulb. If battery voltage does not exist, check wiring. If wiring is okay, check front dome light switch and bulb.
