Tools You'll Likely Need:
* Repair manual: Absolutely crucial for specific instructions and diagrams.
* Screwdrivers: Various sizes of Phillips and flathead.
* Socket set: Metric, likely including various sizes of sockets and extensions.
* Pliers: Needle-nose and possibly regular pliers.

General Steps (Consult your repair manual for specifics):
1. Disconnect the Battery: This is crucial for safety to prevent short circuits.
2. Prepare the Dashboard for Access: This is the most involved part. You'll likely need to:
* Remove the radio: This often involves releasing the radio's mounting brackets.
* Remove various trim pieces: This usually involves carefully prying off plastic trim pieces around the dashboard and center console. Take your time and be gentle to avoid breaking clips. Your repair manual will show you where to start and how to remove the pieces without damage. Take pictures as you go to remember how to reassemble.
* Potentially remove the glove box: In some cases, you might need to remove the glove box for better access.
3. Locate the Air Blend Actuator: Once you have access, locate the actuator. It's usually mounted on the HVAC housing, often under or near the blower motor. The repair manual will show its exact location.
4. Disconnect the Actuator: Disconnect the electrical connector from the actuator. You may also need to disconnect any linkage or cables connected to the actuator.
5. Remove the Actuator: Carefully remove the actuator from its mounting position. There may be screws or other fasteners holding it in place.
6. Install the New Actuator: Install the new actuator in the same position as the old one, ensuring it's properly seated. Reconnect any linkages or cables.
7. Reconnect the Electrical Connector: Securely reconnect the electrical connector.
8. Reassemble the Dashboard: Carefully reassemble the dashboard components in reverse order of disassembly. Make sure all trim pieces are properly snapped into place.
9. Reconnect the Battery: Reconnect the battery.
10. Test the System: Turn on the ignition and test the air blend function to ensure the new actuator is working correctly.
Important Considerations:
* Repair Manual: A repair manual specific to your 1998 Buick Intrigue is essential. Generic instructions can't account for variations in your specific model.
* Patience: This is a time-consuming job. Allow plenty of time to avoid frustration.
* Take Pictures: Take pictures as you disassemble the dashboard to help you reassemble it correctly.
* Fragile Clips: Dashboard trim clips can easily break. Work carefully to avoid damage.
If you're not comfortable with this level of automotive repair, it's best to take your Intrigue to a qualified mechanic. Improperly reinstalling the dashboard can lead to further problems.
