To find it:
1. Locate the fuse panel under the dash: This is usually a large plastic box, often under the steering column or near the driver's side knee.
2. Consult your owner's manual: Your owner's manual will have a diagram showing the location of all fuses and relays. Look for the diagram of the interior fuse panel. The blower motor relay will be labeled.
3. Check for markings: The relay itself may be marked "blower motor" or have a symbol indicating its function. Relays are usually square or rectangular and have multiple terminals.
If your owner's manual is unavailable:
* Online resources: Searching online for "2000 Chevy Silverado blower motor relay location" along with your specific trim level (e.g., 1500, 2500, etc.) might yield images or forum posts showing the exact location.
* A qualified mechanic: If you're uncomfortable working on your vehicle's electrical system, a mechanic can easily locate and diagnose the problem.
Remember to always disconnect the negative battery terminal before working on any electrical components in your vehicle.
