To find the correct fuse, you must consult your owner's manual. The manual will have a fuse box diagram showing the location and function of each fuse.
If you don't have the owner's manual, you can try:
* Online resources: Search online for "1991 Ford Ranger fuse box diagram" along with your engine size (e.g., "2.3L" or "4.0L"). Many websites offer diagrams, but be sure to double-check the year and engine to ensure accuracy.
* Ford dealership or parts store: A Ford dealership or a local auto parts store with knowledgeable staff may be able to help identify the correct fuse.
Caution: Always turn the ignition off before checking fuses.
