To be certain:
1. Consult your owner's manual: This is the best source of information. The manual will have a diagram of the fuse box showing the location and amperage of each fuse.
2. Look for the fuse box diagrams: Sometimes a diagram is affixed to the inside of the fuse box lid.
3. Check online resources: Websites like Dodge forums or repair manuals for the 2006 Caravan may provide the information you need, including photos of the fuse box.
Remember to always turn off the ignition before checking or replacing fuses.
