The cabin air filter in older Buick LaCrosse models is located under the trim panel beneath the right front wiper blade. Steps to replace the cabin air filter: 1. Remove the sealing strip under the passenger side wiper and take out two plastic clips. 2. Remove the wiper cover panel. 3. Take off the cabin air filter cover to access the filter, then remove the old filter and install the new one. 4. Reinstall the cabin air filter cover, wiper panel, sealing strip, and plastic clips back to their original positions. Functions of the cabin air filter: 1. Provide fresh air. 2. Ensure safety and hygiene. 3. Adsorb harmful substances. 4. Filter solid impurities.
My old Buick LaCrosse is a 2008 model, and the cabin air filter is hidden in the footwell area on the passenger side. You'll need to fully open the glove compartment first, then press open the small clips on both sides to remove it. Behind it, you'll see a plastic cover—lift it, and the filter is inserted inside. I've changed it several times myself. Before, I didn't pay attention, and the filter got moldy, causing a foul smell in the car. Later, I learned my lesson and now replace it every six months. The filter size is standard, so you can buy a universal one—just make sure to align it with the arrow direction when inserting it back, as putting it in backward will block the airflow. As a reminder, empty the glove compartment first to avoid dropping items into the air intake, which could cause big trouble.
As someone who frequently performs DIY car maintenance, I find the cabin air filter location on the old Buick LaCrosse very well-designed - it's right above the footwell on the passenger side. The process is straightforward: first unlock the glove compartment door, firmly press the side clips to remove the entire glove box, and you'll see the filter slot positioned centrally. Simply pull out the old filter and replace it with a new one. Make sure to use the correct filter model - the LaCrosse's filter effectively traps dust and pollen. If left unchanged for too long, it can block airflow and reduce AC performance. The whole DIY process takes about 15 minutes, saving significant money compared to shop visits while preventing allergy issues caused by air pollution. I recommend beginners watch tutorial videos before attempting.
