3 Answers
The steps to remove the cabin air filter in a Buick Envision are as follows: 1. Locate the cabin air filter: The cabin air filter in the Buick Envision is installed under the front passenger footwell, near the left foot position, towards the inner side. 2. Use a flathead screwdriver to firmly push and pull it outward. 3. Insert your fingers inside and pull out one corner of the cabin air filter first, then proceed to pull out each corner one by one. The cabin air filter is categorized into three types: standard cabin air filter, single-layer activated carbon series cabin air filter, and multi-layer activated carbon series cabin air filter. Details are as follows: 1. Standard cabin air filter: Made from a specific eco-friendly filtration material processed and folded, usually white and single-layered. 2. Single-layer activated carbon series cabin air filter: Composed of two layers of non-woven fabric (nonwoven cloth) with tiny granular activated carbon sandwiched in between to form an activated carbon filter cloth, which is then further processed into a cabin air filter. 3. Multi-layer activated carbon series cabin air filter: Constructed with four layers—a primary filtration layer (standard filter paper), an antibacterial and benzene-removal layer (special chemical impregnation technology), a deodorization layer (activated carbon layer), and a dust removal layer (electrostatic nonwoven fabric).
I've changed the cabin air filter on my Buick Envision several times, and it's not a difficult job. First, open the glove compartment on the passenger side and remove all items inside. Then, press the retaining clips on both sides of the glove compartment inward to lower it completely. You'll see a rectangular cover with clips, which can be easily removed by pressing gently. When pulling out the old air filter, remember the direction of its arrow—the new filter must be installed with the same orientation, usually with the arrow pointing toward the rear of the vehicle. After installing the new filter, snap the cover back into place and push the glove compartment up until it clicks shut. No tools are needed for the whole process, but be careful not to break the plastic clips. As a reminder, it's recommended to replace the filter every six months to prevent musty odors when using the AC. Doing it yourself takes just over ten minutes and saves you more than 200 yuan compared to going to the dealership.
Friends with strong hands-on skills can try replacing the Envision's cabin air filter themselves. The operation location is behind the glove compartment on the passenger side: First, empty the glove box, then press the plastic limit blocks on both sides of the compartment inward with both hands to fully lower the glove box. The exposed rectangular plastic cover is the filter compartment door, which can be removed by pressing the latch on the edge of the cover. When pulling out the old filter, pay special attention to the arrow direction; the new filter must be installed with the same orientation, usually with the arrow pointing toward the rear or bottom of the vehicle. The key point of the operation is to align the limit clips on both sides with the tracks and push them all the way in when reinstalling the glove box, ensuring a click sound indicates proper placement. The filter costs around 30-50 yuan, and you can buy branded parts like Mann or Mahle online. Avoid using excessive force during the entire process, as plastic components are quite fragile.
