To find the correct fuse:
1. Consult your owner's manual: This is the best resource. It will have a fuse box diagram showing the location and function of each fuse.
2. Check the fuse box itself: The underhood fuse box usually has a diagram printed on the inside of its cover, indicating which fuse controls what circuit. Look for labels related to "turn signals," "flashers," "hazard lights," or similar terms.
3. Look for a blown fuse: Visually inspect the fuses listed as candidates for the flashers. A blown fuse will often have a broken filament visible inside the glass.
If you can't find the information in your owner's manual or on the fuse box cover, a search online using "1998 Ford Explorer Sport fuse box diagram" along with your specific trim level (e.g., Sport, XLT, etc.) might yield a diagram. However, always verify any online information against your vehicle's actual fuse box.
