* Under the hood in the power distribution center (PDC): This is the most common location. The PDC is often a large fuse box/relay center located under the hood, usually near the battery. You'll need to consult your owner's manual or a wiring diagram specific to your Caravan's engine to identify the correct relay.
* Inside the passenger compartment fuse box: Less common, but possible. Again, you'll need a wiring diagram or your owner's manual.
* On the chassis, near the fuel pump: This is the least likely place, but some vehicles might have the relay mounted closer to the component it controls.
To find it, you'll need:
1. Your owner's manual: It *might* show the location of relays.
2. A wiring diagram: This is the best resource. You can often find free diagrams online by searching for "[Your Caravan's Engine] wiring diagram" or visiting a site specializing in automotive repair information (like AllDataDIY or Mitchell 1). The diagram will show the relay's location and what it looks like.
3. A multimeter (optional but helpful): If you can identify the fuel pump wire, you can use the multimeter to trace the circuit back to the relay.
Important Note: Working with car electrical systems can be dangerous. If you're not comfortable with this, take your Caravan to a qualified mechanic. Incorrectly working with the fuel system can be extremely hazardous.
