Tools You'll Likely Need:
* Screwdrivers (Phillips and possibly flathead)
* Socket wrench and sockets (sizes may vary)
* Possibly pliers or needle-nose pliers
* New blower motor resistor (ensure you get the correct part number for your Grand Am)
General Steps:
1. Disconnect the Battery: This is crucial for safety to prevent accidental shorts or electrical shocks. Disconnect the negative (-) terminal first.
2. Locate the Blower Motor Resistor: The resistor is usually located behind the glove compartment (dashboard), under the dashboard near the blower motor, or sometimes even in the engine compartment near the blower motor. This is the most variable step. Your best bet is to consult a repair manual or search online for images showing the resistor's location in a 2000 Pontiac Grand Am. Look for a small, usually black, plastic box with several wires connected to it.
3. Access the Resistor: This might require removing the glove compartment entirely, partially removing the dashboard trim, or accessing it through an access panel. Again, a repair manual will give you the best instructions. This often involves removing screws and potentially some plastic clips.
4. Disconnect the Electrical Connectors: Carefully unplug the electrical connectors from the blower motor resistor. Take note of their positions for reassembly. Sometimes gently prying the connectors apart with a small flathead screwdriver is necessary.
5. Remove the Resistor: Once the connectors are disconnected, the resistor should be relatively easy to remove. It may be held in place with screws or clips.
6. Install the New Resistor: Carefully install the new blower motor resistor, ensuring it's seated correctly. Reconnect the electrical connectors, making sure they're securely attached.
7. Reassemble: Put everything back together in reverse order of disassembly.
8. Reconnect the Battery: Reconnect the positive (+) battery terminal.
9. Test: Turn on your vehicle's ignition and test the blower motor on all speeds. If it works correctly on all speeds, you've successfully replaced the resistor.
Important Considerations:
* Repair Manual: Using a repair manual specific to your 2000 Pontiac Grand Am is highly recommended. It will provide detailed diagrams and instructions tailored to your vehicle.
* Photography: Take pictures as you disassemble the components. This will be invaluable when reassembling.
* Patience: This process can be time-consuming and may require some patience, especially if accessing the resistor requires significant disassembly.
* Safety First: Always disconnect the battery before starting any electrical work.
If you are not comfortable working on your car's electrical system, it's best to take it to a qualified mechanic. Improperly installing the resistor could damage other components.
