Where Is the Cabin Filter on a Chevy Silverado?by Leonardo R. Grabkowski
Chevrolet Silverados built between 1999 and 2002 have cabin air filters, but Silverados manufactured from 2003 to 2010 do not. The Silverado shares major components, including the air filter, with other GM trucks and SUVs, including the Sierra, the Tahoe, and the Suburban.
Silverado Cabin Filter Location
The Chevy Silverado's cabin air filter is mounted under the dashboard, slightly left of center beneath the glove box. The cabin filter is hidden behind a large black cover.
Replacing the Cabin Filter
Replace the Silverado's cabin air filter by removing the four screws from the black cover. Once the cover is off, you'll see an additional screw. Remove it and the panel it's attached to. You'll now see the cabin air filter. Pull it straight down to remove it. Insert a new one if needed, and replace the panels and screws. The cabin air filter should be replaced annually.
Cabin Filter Functions
The Silverado's cabin air filter functions to keep the air in the truck's cab fresh. It filters the air that is circulated through the interior by the air-conditioning vents. Over time, the filter becomes clogged.
