The cabin air filter on most 2015 GMC models sits behind the glove box on the passenger side, and you access it by opening and lowering the glove box to reach a rectangular filter housing. Replace it with the airflow arrows pointing in the correct direction.
Although this is the common setup, some 2015 GMC models have the filter in slightly different spots or require removing additional trim to reach the housing. The exact procedure can vary by model and trim, so consult the owner’s manual or a repair guide for your vehicle if you’re unsure.
Common location and replacement steps
These steps outline a typical access method used by many 2015 GMC vehicles. If your model differs, refer to the manual for model-specific details.
- Open the passenger-side glove box and remove or loosen its contents.
- If present, disconnect or unhook the glove box damper so the box can drop lower.
- Squeeze the sides of the glove box to release the bottom stops and allow the door to swing down fully.
- Look for a rectangular housing behind the box containing the cabin air filter; release any latches or screws and remove the cover.
- Pull out the old filter, noting the orientation of the arrows that indicate airflow.
- Insert a new filter with the correct orientation, then reattach the housing cover and secure the glove box.
Replacing the filter is a routine maintenance task that helps preserve interior air quality and HVAC performance. If you notice reduced airflow, unusual odors, or visible debris, replace the filter and inspect the housing for blockages.
