Diagram of Buick Lesabre ecm location?

There isn't a single diagram applicable to all Buick LeSabres across all model years because the ECM (Engine Control Module) location varied. The location depends on the year, engine type, and sometimes even the specific options on the vehicle.

To find the ECM location in *your* Buick LeSabre, you need to know the year and model of your car. Once you have that information:

* Consult your owner's manual: This is the best place to start. The manual should have a diagram showing the location of major components, including the ECM.

* Use a Haynes or Chilton repair manual: These manuals are readily available online and in auto parts stores, and contain detailed diagrams and descriptions for specific years and models.

* Search online forums: Search online forums specific to Buick LeSabres (e.g., Buick forums on sites like Facebook groups or dedicated car forums) mentioning your year and model. Someone might have already posted a picture or description of the location.

* Look under the hood: The ECM is usually mounted on the firewall, under the dashboard, or near the battery, but it's often hidden and may require removing some trim or other components to see it. Be aware that it's often a small, black box. Look for wiring harnesses leading to the unit and it might have identifying labels on it.

Without the year and model of your Buick LeSabre, it's impossible to provide a specific diagram or location.
