Where is the PCM on a 1998 Buick regal?

The PCM (Powertrain Control Module) on a 1998 Buick Regal is typically located under the dashboard, on the passenger side. However, it's not always in the exact same spot across all models. It's often tucked away and might require removing some trim panels to access.

To be certain, you should:

* Consult your owner's manual: This is the best source of information for the specific location in your vehicle.

* Look for a fuse box diagram: The fuse box cover (usually under the hood or dashboard) often has a diagram showing the location of major modules.

* Search online for a 1998 Buick Regal repair manual: These manuals will show detailed diagrams and instructions. Be sure to specify the engine size (e.g., 3.1L, 3.8L) as the location might vary slightly based on the engine.

Important Note: Before attempting to access the PCM, disconnect the negative battery terminal to prevent electrical shorts. Also, be aware that working with car electronics can be delicate, and if you're unsure, seeking professional help is always the safest option.
