To find them, you need to consult your owner's manual. The manual will have a detailed fuse and relay diagram showing exactly where each one is located, labeled clearly.
Without the owner's manual:
Your best bet is to:
1. Check the fuse box under the hood: This is usually a large box, often black, with a cover that can be opened to reveal several fuses and possibly some relays. Look for a fuse labeled "Windshield Wipers," "Wipers," or something similar. There may also be a separate fuse for the wiper motor itself.
2. Check the fuse box inside the vehicle: Many Ford Explorers also have a smaller fuse box inside the cabin, often located under the dashboard. Check there as well.
3. Look for a relay box: Relays are often grouped together in a separate box, sometimes near the fuse box. Check for a relay marked as being for windshield wipers or wash/wipe.
Important Note: Before touching any fuses or relays, turn off the ignition. Also, visually inspect the fuses first for a blown element (a broken wire inside the fuse). If you find a blown fuse, replace it with one of the same amperage rating. If the fuse blows again immediately, there's a short circuit in the system that needs professional attention. Don't just keep replacing the fuse.
Remember, using the owner's manual is the most reliable way to find the correct fuse and relay for your specific vehicle.
