The inertia switch on a Chevy Tahoe is typically located
under the driver's side of the dashboard. However, the exact location can vary slightly depending on the model year. It's often near the fuse box or other electrical components. You might need a flashlight to find it.
To be sure, I recommend checking your Tahoe's owner's manual. The manual will have a diagram showing the precise location of the inertia switch and other important components.
