Where is the body control module located

What is your question?

In my 08 Pontiac Grand Prix, my doors won't lock properly. I was thinking about replacing the actuators but, an electrical tech told me it could be the fuse if not relay. Come to find out the relay is sodered to the BCM. Any clue?

What makes this problem better or worse?

None

How long has your 2008 Pontiac Grand Prix had this problem?
