To find it, you'll likely need to:
* Look behind the lower dash panel: This often involves removing a few screws or clips to access the area.
* Feel around for a small, square-shaped box: The switch itself is usually quite small and might have a red button or reset lever.
* Check the owner's manual: Though not guaranteed, your owner's manual might show a diagram of the switch's location.
If you can't find it after a thorough search in the suggested area, you might need to consult a repair manual specific to your 1998 Ford Ranger XLT or contact a Ford dealership for assistance.
