To find it, I strongly recommend:
1. Consult your owner's manual: This is the best place to start. It should have a diagram of the fuse and relay boxes.
2. Check the underhood fuse box: This is the most likely location. Look for a box labeled "fuse box" or "relay center," often near the battery or along the fender well. The relays are usually small, square or rectangular components that may be labeled.
3. Look for a diagram on the fuse box cover: The cover itself often has a diagram showing which relay controls what. Look for something indicating "cooling fan," "radiator fan," or a similar label.
4. Use a wiring diagram: If you can't find it visually, you'll need a wiring diagram specific to your 1991 Camaro's engine (V6 or V8) and options. You can often find these online through forums dedicated to Camaros or by purchasing a repair manual (like a Haynes or Chilton manual). These diagrams show the relay's location in the circuit.
Important Note: Always disconnect the negative battery terminal before working with electrical components. This prevents accidental shorts or damage to your vehicle's electrical system.
