How do you remove headliner on a 2001 Oldsmobile intrigue?

To remove the headliner from a 2001 Oldsmobile Intrigue, start by taking out any trim pieces, such as the A-pillar covers, sun visors, and overhead console. Next, carefully detach the headliner from the attachment points, which may include clips or adhesive. Once free, gently lower the headliner and slide it out of the vehicle, being cautious not to damage any surrounding components. Ensure the new headliner is properly installed by reversing the steps.
