The cabin air filter in an older Buick LaCrosse is located inside the glove compartment on the passenger side. Replacement method: 1. Use a screwdriver to gently pry open the right side gap of the plastic panel on the glove compartment; 2. Remove the screws inside with the screwdriver; 3. Press the plastic clips on the panel while pulling it outward; 4. After removing the panel, the cabin air filter will be visible; 5. Replace with a new filter and reinstall in reverse order. The LaCrosse is a mid-to-high-end sedan launched by Shanghai GM, with dimensions of 5005mm in length, 1858mm in width, and 1500mm in height.
In my experience repairing many older Buick LaCrosse models, the location of the cabin air filter is quite straightforward. It's hidden on the passenger side of the engine compartment, right below the windshield. Specifically, you'll need to open the black plastic cover, where you'll likely find the filter housed inside, typically designed in a square or rectangular shape. Before replacing it, it's best to turn off the engine and wait a few minutes to avoid burns. Then, gently pry open the cover screws with a flathead screwdriver, and when pulling out the old filter, remember not to reverse the airflow direction. Many car owners overlook this spot and end up paying high prices at shops for replacement, when in reality, it's a 15-minute DIY job with simple tools. It's recommended to replace it annually, especially when there's an odd smell from the AC, to maintain fresh and clean cabin air and prolong the AC system's lifespan. The older models were designed this way for easy maintenance, while newer models might have changed the location. Regardless, this classic spot is perfect for DIY.
