* Under the hood, in the fuse box: This is the most common location. The fuse box is usually located on the driver's side fender well, or sometimes near the battery. The relay itself will either be labeled clearly (look for "starter," "STR," or a similar marking), or you might need to consult your owner's manual or a wiring diagram to identify it based on its position and circuit.
* On the starter itself: While less common, some 1994 Silverado models might have the starter relay mounted directly on the starter motor. This would require removing the starter to access it.
To find it definitively:
1. Consult your owner's manual: This is the best resource. The manual will have a diagram of the fuse box and relay locations.
2. Use a wiring diagram: A wiring diagram for your specific year, make, model, and engine will show you exactly where the starter relay is located and what its connections are. You can often find these online through repair manuals or automotive parts websites.
3. Visual inspection: Carefully examine the fuse box under the hood. Look for a relay that's larger than the others (starter relays are usually a bit bigger) and might have markings indicating its function.
Remember to disconnect the negative terminal of your battery before working with electrical components in your vehicle.
