How do you replace the cabin air filter on a 1999 BUICK park avenue?

To replace the cabin air filter on a 1999 Buick Park Avenue, first, locate the filter compartment, which is typically behind the glove box. Remove the contents of the glove box and detach it by squeezing the sides to release the stops, allowing it to swing down. The filter is housed in a rectangular compartment; remove the old filter and insert the new one, ensuring the airflow direction matches the markings. Finally, reattach the glove box and close it.
