Where is the ecm located on a 1997 GMC safari?

The Engine Control Module (ECM) on a 1997 GMC Safari is typically located under the dashboard on the driver's side. It can be found mounted to the firewall, behind the glove compartment area. To access it, you may need to remove some panels or the glove box itself. Always ensure the vehicle is off and the battery is disconnected before attempting to work on the ECM.
