Here's a general guide. You should consult a repair manual specific to your 2002 Chevrolet S10 for precise instructions and diagrams. These manuals often show the exact location and provide detailed steps.
1. Locate the Blower Motor Resistor:
* Most common location: The blower motor resistor on many S10s is located behind the glove compartment. You'll likely need to remove the glove box to access it.
* Other possible locations: Some models might have it under the dashboard, requiring more disassembly. Again, your repair manual is key here.
2. Remove the Glove Box (if necessary):
* Usually, this involves removing screws or clips holding the glove box in place. Carefully release the box and set it aside.
3. Access the Blower Motor Resistor:
* Once the glove box is out (if applicable), you should see a small electrical component, often a black plastic box or module. This is likely the blower motor resistor. It's usually connected to the blower motor wires.
4. Disconnect the Electrical Connectors:
* Carefully unplug the electrical connectors attached to the blower motor resistor. Take note of how they are connected to ensure you reassemble correctly. A photo can be helpful.
5. Remove the Blower Motor Resistor:
* The resistor might be held in place by screws, clips, or simply friction. Carefully remove it from its mounting location.
6. Install the New Blower Motor Resistor:
* Carefully install the new blower motor resistor in the same location as the old one. Make sure it's securely fastened.
7. Reconnect the Electrical Connectors:
* Carefully reconnect the electrical connectors to the new blower motor resistor, ensuring they are securely plugged in.
8. Reinstall the Glove Box (if necessary):
* Carefully put the glove box back in place and secure it with the screws or clips.
9. Reconnect the Battery Negative Terminal:
* Reconnect the negative battery terminal.
10. Test the Blower Motor:
* Turn on the ignition and test all blower motor speeds. If it's working correctly, you've successfully replaced the resistor.
Important Considerations:
* Repair Manual: A repair manual specific to your 2002 Chevrolet S10 is highly recommended. It will provide detailed diagrams and instructions, preventing potential damage.
* Safety: Always disconnect the negative battery terminal before starting any electrical work to prevent shocks and short circuits.
* Parts: Ensure you purchase the correct blower motor resistor for your specific vehicle. The part number should be on the old resistor, or you can find it using your vehicle's VIN.
If you're uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. Improperly replacing the resistor could lead to further damage.
