Where is the Buick's air filter located?
3 Answers
The Buick's air filter is located behind the passenger glove box. The functions of the air filter are: 1. Provide fresh air; 2. Ensure safety and hygiene; 3. Absorb harmful substances; 4. Filter solid impurities. The steps to replace the air filter are: 1. Open the passenger glove box and you will find a cover plate; 2. Press the cover plate buckle inward with your hand to remove the cover plate, and you will see the internal air filter housing; 3. Remove the air filter housing and install the new air filter. Buick models include: Buick GL8, Buick Excelle, Buick Regal, Buick LaCrosse, Buick Envision, etc.
I've been driving a Buick for several years and often change the air conditioning filter myself, which is located behind the glove compartment in front of the passenger seat. The method is quite simple: first, empty the glove compartment, locate the plastic clips on either side or at the bottom, gently press them to remove the glove compartment assembly, and then the filter housing will be exposed. Just pull open the cover and replace it with a new filter. Different Buick models like the Regal or GL8 have similar designs, making it easy to replace. It's recommended to change it every 15,000 kilometers or once a year; otherwise, dust and pollen buildup in the air can not only cause a musty smell when the AC is on but also increase the blower's load and shorten its lifespan. Especially for city driving, frequent replacement is advised, as filtering PM2.5 is particularly helpful for people with rhinitis, and doing it yourself saves on repair costs.
The cabin air filter is typically located behind the glove compartment in Buick vehicles. After removing the glove box, you can see the filter housing. To access it, open the glove box, empty its contents, then release the side clips without forcing them to avoid damaging plastic components. Some owners skip this step and risk scratching parts while searching. No tools like screwdrivers are needed—it's a manual process. Replacement is recommended annually or every 20,000 km, adjusted for air quality (e.g., every 6 months near construction sites). Ensure proper installation for a tight seal to prevent dust from entering the AC system, which increases energy consumption. Select the filter model per Buick’s manual—its stable position simplifies maintenance, ensuring fresh cabin air and reduced allergens.
