I'd be looking at the wire harness where it goes into the trunk lid. My
guess is that the wires going to the license plate light are broken due to
the flex that comes from opening and closing the trunk.
Thanks Jeff and Petrus -
I would agree except that the trunk lights go on at exactly the same time
that the lic plate lights go off. Since I just bought the car, I dont know
how the lights are supposed to work. But this is how it works now: When
you pop the trunk the lic plate lights turn on. As the trunk lid hits the
top stop, the lic plates turn off (which also illuminate the trunk area) and
the trunk lights turn on. These lights behave the same way whether the
headlights are on or off. The only problem is that the lic plates never
turn on when the headlights turn on. So, it may be that the current on/off
behavior is normal (but I dont know since I just bought the car) but the
switch over between lic plate lights and trunk lights is exactly the same
time - like they were being controlled by a switch. Is there a lic plate
light sending unit somewhere that I should check? Anyone have an E32 or E34
that can verify that this behavior is normal?
1. Bad connection... when you lift the trunk, it moves the wires around and
makes a good connection. Wiggle things and see.
2. Bad ground... but when the trunk light is turned on, the license plate
lights get grounded through the trunk light circuit.
