* Under the hood, in the Power Distribution Center (PDC): This is a large fuse and relay box, often located near the battery. The PDC usually has a diagram on the cover identifying the relays. Look for a relay labeled "cooling fan," "radiator fan," or something similar.
* Under the dash: Less common, but some models might have it tucked away under the dash, possibly near the fuse box located there.
To find it, I recommend:
1. Consult your owner's manual: This is the best place to start. The manual should have a diagram of the fuse and relay boxes, clearly showing the location of the cooling fan relay.
2. Check the Power Distribution Center (PDC) first: This is the most likely location. Open the hood and look for a large rectangular box with many fuses and relays. The cover should have a diagram.
3. Use an online parts diagram: Websites like AutoZone, Advance Auto Parts, or RockAuto often have detailed diagrams of your vehicle's fuse and relay boxes. Search for your specific 1999 Dodge Caravan year, make, model, and engine. These diagrams usually show the location of each component.
4. If all else fails, search online forums: Search for "1999 Dodge Caravan cooling fan relay location" on forums like DodgeForum.com. Other owners might have posted pictures or descriptions of where they found theirs.
Remember to disconnect the negative battery terminal before working with any electrical components. This is a crucial safety precaution.
