The most common location is in the Power Distribution Center (PDC), which is a large black box often located near the battery in the engine compartment. However, some models might have it in a smaller relay/fuse box nearby.
To find it:
1. Locate the PDC: This is the biggest box, often with many relays and fuses.
2. Consult your owner's manual: This is the best resource, as it will have a diagram showing the relay locations.
3. Look for a relay that's labeled: It might be explicitly labeled "Cooling Fan" or something similar. If not, use the diagram from your owner's manual to identify the correct relay based on its circuit description.
4. If you cannot find it in the PDC, look in any other fuse/relay boxes located near the PDC or elsewhere under the hood.
If you don't have an owner's manual: A search online for "1996 Dodge Grand Caravan cooling fan relay location" along with your engine size (3.0L or 3.3L) may provide diagrams or forum posts that can help. Remember that pictures from other years might be slightly different.
Important Note: Working on your vehicle's electrical system can be dangerous. If you are not comfortable working with car electrical systems, take your vehicle to a qualified mechanic.
