To locate it, you might need to:
* Consult your owner's manual: This is the best place to start. It should have a diagram showing the location of all important components, including the inertia switch.
* Look for a small, usually red, square box: Inertia switches are often easily identifiable by their size and color.
* Remove some trim panels under the dash: This might be necessary to access the switch if it's not immediately visible. Be careful when doing this to avoid breaking any clips.
If you can't find it after searching these areas, a search online for "1997 Chevy Tahoe inertia switch location" alongside images might help you visually identify it. A mechanic would also be able to locate it quickly.
