* Under the hood, in the Power Distribution Center (PDC): This is a large fuse and relay box, usually located near the battery or firewall. The PDC is the most likely location. You'll need to open the PDC cover (often held on by screws or clips) and consult a wiring diagram or the PDC's label to locate the specific relay. The relay may be labeled, or you might need to trace wires to identify it.
* In the under-dash fuse box: Less common, but possible on some models. Again, a wiring diagram would be necessary for identification.
To find it definitively:
1. Consult your owner's manual: The manual should have a diagram showing the location of the fuse and relay boxes, and possibly even the specific location of the cooling fan relay.
2. Use a wiring diagram: A wiring diagram specific to your 1996 Dodge Caravan's engine (e.g., 3.0L, 3.3L, 3.8L) will show the relay's location and its connections. You can find these diagrams online (often for a fee) or at an auto parts store.
3. Trace the wiring: Locate the cooling fan motor and trace the power wires back to the fuse and relay boxes. This method takes more time but works if you can't find a diagram.
Important Note: Before working on any electrical components, disconnect the negative battery terminal to avoid electrical shocks or damage.
