Your GM vehicle relies on two kinds of air filters. One is for your engine, and the other is for your air and heating systems. They both help to protect important systems from contaminants and debris. In that way, they work much the same as your oil filter and fuel filter do.
Where to Find Your Air Filters
Your engine air filter is typically located near the air intake, where it captures pollutants before they can get into the engine and collect on your spark plugs or fuel injectors.
The cabin air filter can usually be found in one of three locations. Usually, it's behind your glove compartment. Some vehicles may put it under the front cowling on the passenger side of your vehicle, or under the dash on the passenger side of the cabin. It prevents allergens and irritants from traveling through the air vents into the air that you breathe in.
Unfortunately, your air filters will either degrade with age or get too clogged up to allow unrestricted airflow. When that happens, they need to be replaced.
How to Spot Air Filter Issues
Signs of trouble include:
- The "Check Engine" light comes on
- Engine misfires
- Weakened throttle response
- Odd engine noises
- Reduced engine power
- Worsening fuel economy
- The cabin sells musty
- A whistling sound coming from the air vents
