I have a BMW 323is and the trunk light stays on. We have to slam the
trunk several times to get the light to go out and then we can lock
the car w/remote.
If the trunk lid is up and I depress the trunk switch/plunger the
light goes out and you can lock the car w/remote. If the trunk lid
is near closed (less than 6 inches open) depressing the plunger has no
effect. Like there is a second position switch somewhere that detects
a slightly open lid.
Any thoughts on this or am I chasing a different problem.
Is that a simple circuit, I looked at the plunger/switch and it breaks
the connection when the trunk is closed.
I assumed this turned out the light. Does it do more ?
Does it trigger some logic that turns out the light and reports the
state of the trunk lid ?
I don't know how it is on the 325. I just can describe the Z3 coupé, hoping
that this will help you.
The switch is located just below the latch, refer to the picture
Two small (~4mm) round nail heads like black clips can be visible through
the clearance (see the arrow).
For mounting, the switch slides into two key hole shaped slots. It is
engaged by the inside.
Nothing seems to clamp it. On my car, it happened to escape from the "key
holes". The contact was randomly established.
It's rather easy to fix it, passing the hand between the black cable and the
There's a specific position for the latch to allow the mounting. I can't
remember if it needs to be open or closed.
The plunger has worn so it's shorter than it's supposed to be. That's
why slamming the lid deflects the metal and turns the light out. You
can glue on an improvised cover of something plastic to make the
plunger longer again. In the reverse condition if the phillips screw
that holds the switch in is even slightly loose you will get no trunk
I have a 325 and I can only see one trunk light switch to the left of
the latch right next to the light.
