Yes. The 2015 GMC Sierra 1500 generally includes a cabin air filter (also called a pollen filter) as part of the HVAC system, and it is typically located behind the glove box. Replacing it is a standard maintenance task to keep interior air clean.
Where the filter sits and how to check
To confirm whether your exact vehicle has a cabin air filter and to locate it, follow these steps.
- Consult the owner’s manual for the cabin air filter or pollen filter section.
- Inspect the passenger-side area behind the glove box for a rectangular filter housing.
- Look for a panel or cover secured with screws or clips that can be removed to reveal the filter.
- If you don’t find a housing behind the glove box, your vehicle may have a different HVAC configuration or could be missing the filter in very early production; consider checking with a dealer or service bulletin.
Carrying out these checks will help confirm presence and location. If you do see the housing, you’re likely dealing with a standard cabin air filter and can proceed to replacement as needed.
How to replace the cabin air filter
When replacement is due, follow these steps to swap in a new filter with minimal hassle.
- Park on a level surface and turn off the engine. For safety, engage the parking brake.
- Open the glove box and remove contents; if the box has dampers or stops, disconnect them so the box can drop downward.
- Support the glove box as it drops to access the filter housing behind it; locate the housing cover secured by clips or screws.
- Remove the filter housing cover and take out the old filter, noting the correct orientation of the filter arrows pointing toward the blower motor.
- Clean the housing if there is dust; insert the new filter in the same orientation as the old one, ensuring a snug fit.
- Reattach the housing cover, re-secure the glove box, and restore its stops or dampers.
- Close the glove box, start the engine, and run the climate control on fresh air to test for proper airflow and to confirm the filter is seated correctly.
After replacement, it’s a good habit to keep an eye on the HVAC performance and replace the filter at intervals appropriate for your environment. In dry, dusty areas or heavy pollutant conditions, replacement may be needed more frequently.
Summary
For the 2015 GMC Sierra 1500, a cabin air filter is typically present and accessible behind the glove box in most trims. Verify with your specific vehicle’s manual or dealer if you’re unsure, then replace at regular intervals to maintain clean interior air and efficient HVAC performance.
