Under the corner of the right windshield. Generally, there are four filters in a gasoline-powered sedan. Corresponding to the engine are the oil filter for filtering engine oil; the air filter for filtering combustion air; and the fuel filter for filtering gasoline. Only the cabin air filter, also known as the interior filter, is used to filter the air inside the car's cabin. Below is related information: 1. LaCrosse: The LaCrosse is a new mid-to-high-end sedan launched by SAIC-GM on February 22, 2006. The "Jun" represents a high-grade, upscale image, while "Yue" carries the meaning of "breakthrough and transcendence." 2. Cabin air filter: It ensures that the filter fits tightly against the housing, preventing unfiltered air from entering the cabin. It separates solid impurities such as dust, pollen, and grinding particles from the air. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air; it has strong and long-lasting moisture adsorption capabilities.

The cabin air filter in older Buick LaCrosse models is typically located behind the glove compartment on the passenger side. After opening the glove box, locate the retaining clips and push them inward or lift upward to fully lower the glove box, revealing the filter cover. Unscrew or simply pry open the cover to remove the old filter and install a new one. The design is quite user-friendly—I've replaced mine several times. Just remember to choose the correct type, either standard or activated carbon. Activated carbon filters provide more thorough filtration and can also absorb odors. It's recommended to replace the filter every six months or 10,000 kilometers. Otherwise, accumulated dust can cause musty smells when the AC is on, affecting respiratory health—especially during pollen-heavy spring and autumn seasons when more frequent changes help maintain fresh cabin air. DIY replacement is extremely simple, saving you the hassle and cost of visiting a repair shop.

For older LaCrosse models, the cabin air filter is mostly located behind the glove box. First, empty the glove box contents, then firmly press the protruding parts on both sides to fully lower it. After removing the inner panel, you'll see the filter housing. Simply pull out the old filter and replace it with a new one, ensuring correct installation direction to avoid airflow blockage. The design is quite user-friendly, allowing owners to DIY without professional skills. As a crucial component of the AC system, neglected filter replacement reduces cooling efficiency and causes odors. Recommended inspection interval is every 8,000 km. Regular maintenance prevents allergies and extends AC system lifespan.

The air conditioning filter in the older LaCrosse is usually hidden behind the glove box. After opening the glove box and lowering it, you can see the cover panel. Removing it makes replacing the filter very simple. The location is convenient and easily accessible, unlike older cars where it's more complicated in the engine compartment. After years of driving, I feel this design enhances convenience—you can replace it yourself without any tools. The filter is responsible for filtering the air and preventing dust from entering. Remember to change it regularly to avoid health issues like coughing or allergies.
