As you can see, it is a bit complicated :
The door switches tell the Central Locking Pump if they are open or closed.
It then sends a tweet to the Body Control Module.
The BCM then supplies a ground to the dome light, then after a period of time it gradually removes the ground so the light seems to just fade out. ( If the dome switch is in the "auto" position. )
Riddle me this.. switch in the "automatic mode" for the dome lights.. lights stay on. They never time out.. as in normally when door is left open after a while they still time out - or when car is started. Put the roadsters (problem car) BCM in my coupe.. works fine. So are we off to check the Security pump module time? If a door switch is bad .. would it prevent the module from eventually timing out?
Lighted door sills await your resolution..
