To find it:
1. Consult your owner's manual: This is the best place to start. The manual should have a diagram showing the location of all fuses and relays.
2. Check the underhood fuse/relay box: This box is usually located near the battery, often on the driver's side fender well. Open the box and look for a diagram inside the cover. The diagram should identify the radiator fan relay. It may be labeled as "Radiator Fan," "Cooling Fan," or similar. The relay itself is typically a square or rectangular component with multiple terminals.
3. Check the passenger compartment fuse box: If you can't find it under the hood, check the fuse box inside the car. This is usually located under the dashboard, often near the steering column or under the glove compartment. Again, check the diagram inside the cover for the radiator fan relay.
4. If you are still having trouble: Look for a wiring diagram specific to your 1995 Dodge Neon's year and model online (many are available on automotive repair sites). These diagrams provide a detailed overview of the vehicle's electrical system and will pinpoint the relay's location.
Important Note: Before working with electrical components, always disconnect the negative terminal of your battery to prevent accidental shorts.
