Wiring diagrams here: http://www.autolib.diakom.ru/CAR/BMW/ Use '89 325i.
The most likely cause of your problem (assuming your car is RH drive) is either the glove box light/switch assembly is falling apart, or has been left with no lamp in it.

Difficult to see how that can happen, unless the actual wire is damaged.
There's still a live wire bouncing around, even if the glove box switch is removed.
