Tools You'll Need:
* New Blower Motor Resistor: Make sure you get the correct part number for your 2000 Chevy Prizm. Auto parts stores can help with this using your VIN.
* Screwdrivers: Likely a Phillips head and possibly a flathead.
* Socket Set (optional): Might be needed depending on how the resistor is secured.
* Needle-nose pliers (optional): Can be helpful for working in tight spaces.
* Gloves (optional): To protect your hands.
Steps:
1. Disconnect the Battery: This is crucial for safety. Disconnect the negative (-) terminal first.
2. Access the Blower Motor Resistor: This is typically located behind the glove box (passenger-side compartment).
* Glove Box Removal: You'll need to remove the glove box. This usually involves removing screws on the sides and possibly at the top. Refer to your repair manual for the exact procedure. Some models might require removing the glove box liner as well.
3. Locate the Resistor: Once the glove box is out, you should see the blower motor resistor. It's a small, usually rectangular, black plastic unit with wires connected to it. It might be attached to the blower motor housing or secured with screws. The location varies slightly between models.
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 correct reassembly. Sometimes, gentle prying with a small flathead screwdriver is necessary.
5. Remove the Old Resistor: Unscrew or unclip the resistor from its mounting location.
6. Install the New Resistor: Carefully install the new blower motor resistor in the same location as the old one. Ensure it's securely fastened.
7. Reconnect the Electrical Connectors: Plug the electrical connectors back onto the new resistor, matching the connections to their original positions.
8. Reassemble: Reinstall the glove box, ensuring all screws are tightened.
9. Reconnect the Battery: Reconnect the negative (-) battery terminal.
10. Test the Blower: Turn on the ignition and test the blower motor on all speeds. If it's working correctly, you've successfully replaced the resistor. If not, double-check all connections.
Important Considerations:
* Repair Manual: A repair manual specific to your 2000 Chevy Prizm is highly recommended. It will provide detailed diagrams and instructions that account for variations in your specific model.
* Safety: Always disconnect the battery before starting any electrical work.
* Pictures: Taking pictures before disconnecting anything can be extremely helpful during reassembly.
* Difficult Access: The access to the blower resistor can be somewhat challenging. Be patient and take your time to avoid damaging any components.
If you're not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. They have the expertise and tools to do the job safely and efficiently.
