* Under the dash: This is the most common location. Look behind the glove box, under the steering column, or near the fuse panel inside the cab. Sometimes it's mounted to the side of the fuse panel itself.
* In the fuse box (underhood, less likely): While less common on S10s for the blower motor, a few years might have it here. Check your owner's manual or a fuse box diagram for your specific vehicle year and model.
To find it:
1. Consult your owner's manual: This is the best starting point. The manual should have a diagram showing the location of all relays and fuses.
2. Check online forums: Search online forums specific to your year and model of Chevy S10. Many owners have documented the location of their blower motor relay. Include your year and engine in your search terms.
3. Use a wiring diagram: A wiring diagram for your specific vehicle will show the location of the relay and the circuits it controls.
4. Trace the wires: If you can't find it using the above methods, you can try tracing the wires from the blower motor itself. Follow the wiring harness back towards the cab; the relay will be somewhere along the route. Be careful not to accidentally damage any wires.
Remember to always disconnect the negative battery terminal before working on any electrical components.
