* Under the hood, in the Power Distribution Box (PDB): This is the most common location. The PDB is usually a large black plastic box near the battery. The relay itself will likely be a fairly standard-looking automotive relay. You'll need to consult your owner's manual or a wiring diagram to identify the specific relay.
* On the fender apron (less common): In some instances, especially with some 4.0L engines, the relay might be mounted on the fender apron near the battery, sometimes attached to the inner fender well.
To find it:
1. Consult your owner's manual: This is the best starting point. It will have a diagram showing the location of relays and fuses.
2. Look in the Power Distribution Box (PDB): Open the hood and locate the large black plastic box near the battery. The lid usually has a diagram showing the location of the fuses and relays.
3. Examine the wiring: Trace the wires leading from the starter motor. These should lead you to the relay.
4. Use a wiring diagram: If you can't find it visually, a wiring diagram specific to your 1997 Ford Explorer's engine and drivetrain will be invaluable. You can usually find these online (some are free, others require a subscription to a repair manual site).
Important Note: Before working on any electrical components, disconnect the negative terminal of your battery to prevent electrical shocks or damage.
