So my interior lights are going out of control.
Where is the BCM? I think it maybe a loose ground or wire to a relay.
What happens is the interior lights take an extra 2 seconds when I turn them off at the head light switch. Also from time to time they stay on with the door closed and doors lock when they should be off. What has me concerned now is driving to work the other day the interior lights flashed as I drove. Thanks for the help.

Sounds like a bad switch inside a door. While inside, grab a door and start pushing and pulling on each door while watching the dome light.

Three things can be at fault.

Door switch (most common)
RFA
MALL (aka BCM)

That'* the order in which the FSM suggests you check/replace as well.

Your BCM and RFA are behind the glove box. Between taking off the hush panel and taking out the glove box, you should have enough room to work.

There'* no room gained by pulling the glove box. Thanks GM for that solid crash bar behind it..

Where are the door switches. (Sorry been working 55hr work weeks, hence the limited forum activity, also the lack of drive to search for switches)
