The ECM (Engine Control Module) on a Chevy Lumina is typically located
underneath the dashboard, on the passenger side. However, the exact location can vary slightly depending on the year and model of the Lumina. It's often attached to the firewall or secured to a bracket.
To be certain, you should consult your Lumina's repair manual or a reliable online resource like a parts diagram specific to your vehicle's year and model. Searching for "[Your Lumina's Year] Chevy Lumina ECM location" online should yield helpful results.
