* Under the hood, in the fuse box: This is the most common location. Open the hood and locate the fuse box (often near the battery or firewall). The relay itself will likely be clearly marked, or you can consult your owner's manual's fuse box diagram. Look for a relay labeled "fan," "radiator fan," or something similar.
* Inside the cabin, under the dashboard: Less common but possible, especially if it's a combined HVAC/engine control system. This would require more extensive searching and potentially removing some dash panels.
To find it definitively:
1. Consult your owner's manual: This is the best source. The diagrams will show you precisely where the relays are located and what each one controls.
2. Use a wiring diagram: A wiring diagram for your specific 1995 Cavalier Z24 will show the path of the fan's power and pinpoint the relay location. You can find these diagrams online (often through forums dedicated to Chevy Cavaliers) or at auto parts stores.
3. Visual inspection (with caution): If you're comfortable working with automotive electrical systems, carefully examine the fuse box and relay locations. Relays are usually square or rectangular, and often have a clicking sound when activated. Be cautious not to touch any exposed terminals or wires.
Remember to always disconnect the negative battery terminal before working on any electrical components in your car.
