1. Preparation:
* Safety First: Disconnect the negative battery cable before starting any work.
* Gather Tools: You'll likely need a screwdriver (likely Phillips head), possibly a socket set (depending on how the resistor is mounted), and potentially some pliers.
* Location: The blower motor resistor is usually located behind the glove box (passenger-side compartment).
2. Accessing the Blower Motor Resistor:
* Remove the Glove Box: This usually involves removing screws or clips holding the glove box in place. Consult your repair manual for the exact procedure; some Intrigues might have different configurations.
* Locate the Resistor: Once the glove box is out of the way, you should see the blower motor resistor. It's usually a small, rectangular or square-shaped component with several electrical connectors. It might be mounted directly to the HVAC housing or secured with screws.
3. Replacing the Resistor:
* Disconnect the Electrical Connectors: Carefully unplug the electrical connectors from the resistor. Take note of their positions to ensure you connect them correctly when installing the new resistor. Take pictures if it helps.
* Remove the Old Resistor: Unscrew or unclip the old resistor from its mounting location.
* Install the New Resistor: Carefully install the new resistor in the same location as the old one. Ensure it's securely fastened.
* Reconnect the Electrical Connectors: Carefully plug the electrical connectors back onto the new resistor, ensuring they are securely connected.
4. Reassembly:
* Replace the Glove Box: Reinstall the glove box, making sure it's properly secured.
* Reconnect the Battery: Reconnect the negative battery cable.
5. Testing:
* Turn on the Ignition: Turn on your car's ignition and test all blower motor speeds. If the problem is solved, all speeds should work correctly.
Important Considerations:
* Parts: Always purchase a replacement blower motor resistor that's specifically designed for your 1998 Oldsmobile Intrigue. Using the wrong part can cause further damage.
* Repair Manual: A repair manual is highly recommended. It will provide detailed instructions and diagrams specific to your vehicle's make and model. Improper installation can lead to further damage or electrical hazards.
* Difficult Access: Accessing the blower motor resistor can be challenging depending on the specific design of your vehicle. If you're uncomfortable performing this repair, it's best to take your car to a qualified mechanic.
This guide offers general steps. Always refer to a repair manual for your specific vehicle for precise instructions. Improper repair can lead to damage or injury.
