The neutral safety switch on a 1998 Buick LeSabre is located on the
transmission. More specifically, it's usually found on the
side of the transmission case, near where the shift linkage connects. However, the exact location can vary slightly depending on the specific transmission type (e.g., 3-speed automatic, 4-speed automatic).
To locate it, you'll likely need to get under the car and look closely at the transmission. It's a relatively small switch and may have wiring connected to it. A repair manual for your specific year and model LeSabre would provide the most precise location and visual aid.
