Where is the cabin air filter in a 2004 Chevrolet astro van?

In a 2004 Chevrolet Astro van, the cabin air filter is located behind the glove compartment. To access it, you'll need to remove the glove compartment door by disconnecting the damper and unfastening the screws or clips that hold it in place. Once the glove compartment is out of the way, you can reach the filter housing to replace the cabin air filter.
