To find it:
1. Locate the underhood fuse box: This is usually a large black box located near the battery, often on the driver's side fender. The cover should have a diagram showing the fuse and relay locations.
2. Consult the fuse box diagram: Your owner's manual should have a detailed diagram of the fuse box. This is the most reliable way to locate the correct relay. Look for a relay related to the starter motor, often indicated by a symbol or the word "START."
3. Look for a high-amperage relay: If the diagram isn't perfectly clear, look for a relay with significantly thicker wires than the others. The starter relay handles a high current to engage the starter motor.
4. Test (optional but helpful): If you're unsure, you can carefully test relays using a multimeter. However, be cautious as working with car electrical systems can be dangerous if not handled correctly.
Important Note: While the above is generally true, the exact location and labeling *could* vary slightly depending on specific options or regional variations. Always refer to your owner's manual for the most accurate information. If you can't find it in the manual, a reputable online parts store or a qualified mechanic can help confirm the relay's location.
