I have a 97 Bonneville SE and the courtesy interior lights won't turn off until the BCM waits 10 minutes. I have replaced the BCM, headlight switch and the drivers door latch/switch combo. I have checked the other door latches too. Nothing has helped so far.
I have pulled the fuse because I can't find the problem. Any suggestions would be appreciated.

There is a separate relay in the relay center. It is an instrument light relay. There is also a remote accessory control modue that might cause the problem because it controls the relay and it has a built in timer.

You also have an adapative light monitor module that has a remote chance of causing the problem.

Let me know
