Buick LaCrosse's air filter is located inside the glove compartment on the passenger side. To replace the filter, you need to first remove the glove compartment and then open the cover of the air filter box to replace it. The replacement cycle for the Buick LaCrosse air filter is generally every 10,000 kilometers. Introduction to the Buick LaCrosse: 1. Exterior Introduction: New wing-shaped air intake grille, wing-shaped full LED headlights, wing-shaped full LED taillights 2. Power Introduction: The 2021 Buick LaCrosse is equipped with a 2.0T variable cylinder turbocharged engine.

I also drive a LaCrosse, and the cabin air filter is located behind the glove compartment on the passenger side. First, empty the glove compartment, then locate the retaining clips on both sides of the glove box. Press both clips inward simultaneously with your hands, and the entire glove compartment will fold downward. You'll see a black plastic cover—gently unclip it and remove the cover to reveal the cabin air filter. Remember, there's an airflow direction arrow on the filter; make sure the arrow faces downward when installing the new one. It's quite simple to replace it yourself—I usually change it every six months, especially during heavy smog days, otherwise the air from the AC will smell dusty. Buying an OEM filter online costs just a few dozen yuan, saving you more than half compared to going to the dealership.

I just replaced the cabin air filter for my wife's LaCrosse, which is located behind the glove compartment on the passenger side. First, you need to open the glove box and empty it. Here's the key part: there are raised plastic clips on both sides of the compartment that you have to press firmly inward to fully lower the glove box. Then you'll see a rectangular cover panel - just pinch the small clips at both ends of the panel and pull to open it. When removing the old filter, remember the direction of the arrow, and insert the new filter in the same orientation. The whole process takes about ten minutes. The only thing to note is not to use excessive force when handling the plastic parts, as the plastic clips on the LaCrosse are quite brittle.

The cabin air filter for the Buick LaCrosse is located behind the glove compartment on the passenger side. To remove it, first adjust the seat backward to create space, then empty the glove box. There are retractable rods on both sides of the compartment - press the inner limit tabs to detach the box. The rear panel has two plastic clips that can be easily flipped open, revealing the hidden filter. When replacing it yourself, make sure to purchase the correct model as LaCrosse filters may vary in size across different model years. It's recommended to replace the filter twice a year, especially when musty odors occur during heater operation or when airflow decreases. DIY replacement is convenient for those with mechanical skills, while those unfamiliar can have it replaced at a repair shop at reasonable cost.
