Where is the body control module on a 2002 Cadillac DeVille?

The Body Control Module (BCM) on a 2002 Cadillac DeVille is located underneath the dashboard, on the driver's side. It's usually fairly deep inside, and you'll likely need to remove some trim panels to access it. There's no single easily accessible location like under the hood or in the trunk for this module.

Because of its location and the need to remove interior components to access it, attempting to locate and access it yourself should only be done if you have experience with automotive electrical systems and interior disassembly. If you're not comfortable with this, it's best to consult a qualified mechanic or auto electrician.
