To find it, you need to:
1. Consult your owner's manual: This is the most reliable source. The manual will have a diagram showing the fuse box locations and a fuse legend identifying which fuse controls the brake lights.
2. Check the fuse box(es): Dodge Caravans typically have at least one fuse box under the hood and one inside the passenger compartment (often under the dash). Look for a cover on these boxes – it will usually have a diagram printed on the inside of the cover showing which fuse is which.
3. Look for labels: Some fuse boxes have labels near the fuses themselves that indicate their function (e.g., "Brake Lights").
Without knowing the year and model of your Dodge Caravan, it's impossible to give a precise location. Always refer to your owner's manual first.
