The steps to replace the air conditioning filter in an old Regal are: 1. Open the glove compartment cover on the passenger side; 2. Press and hold the fixing buckle firmly and pull it outward; 3. After removing the fixing buckle, take off the cover; 4. Remove the entire glove compartment; 5. Dismantle the air conditioning filter cover; 6. When replacing the car's air conditioning filter, grab one end of the old filter and pull it outward to remove and replace it. Taking the 2020 Buick Regal as an example, it belongs to the mid-size car category with body dimensions of: length 4904mm, width 1863mm, height 1461mm, wheelbase 2829mm, fuel tank capacity 55l, and trunk capacity 441l. The 2020 Buick Regal is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 169PS, maximum power of 124kW, maximum torque of 250Nm, paired with a 9-speed automatic transmission.

I've changed the cabin air filter on my old Buick Regal several times myself. The first step is to remove the glove compartment on the passenger side—just apply some pressure to the clips on both sides, and you can take the whole thing off and place it on the floor. Then, you'll see a long black plastic cover, which is the filter housing. Gently release the clips to remove the old filter, and make sure to note the arrow direction—on the Regal, the arrow must point toward the rear of the car when installing the new filter. Installing it backward will reduce airflow. I usually use a vacuum to clean out leaves and dust from the filter slot before inserting the new one, being careful not to bend the foam edges. Finally, snap the cover back on and slide the glove compartment into place along its tracks. Keep a flashlight handy for better visibility during the process. Also, I recommend replacing the filter before each rainy season; otherwise, you might notice a musty smell when you turn on the AC.

Changing the air conditioning filter in an old LaCrosse is actually a matter of minutes. I usually start by clearing out the glove box to avoid any obstructions. There's a damper rod at the bottom of the glove box; just pinch the connector and pull to separate it. Then, press firmly on both sides of the glove box inward until you hear a click, indicating the limit clips have released, allowing the glove box to fully drop down. The filter compartment is hidden behind it; use a flathead screwdriver to pry open the right-side latch of the cover to reveal the filter. Older cars tend to accumulate dust, so before installing the new filter, I wipe the plastic channel clean with a wet wipe. When installing, make sure the pleats on the side of the filter are fully expanded, with the arrow mark pointing toward your toes. Finally, align the glove box with the slots and push it back into place, then test at maximum airflow for five minutes to check for any unusual noises.

For beginners changing the air filter, remember these key points: The LaCrosse's cabin air filter is located inside the glove compartment on the passenger side—no need to remove the center console panel. After opening the glove box, press down the plastic tabs on both sides to let it hang down, then use your fingernail to unlatch the white filter housing. Before removing the old filter, take a photo to note its orientation; install the new filter with the arrow pointing downward. Pay special attention to check if the sealing strip around the filter is deformed—last time I didn't fit it tightly, which caused dust leakage. When reinstalling the cover, secure the bottom first before snapping the top edge. Avoid forcing plastic parts during the process; spraying some WD40 on the glove box tracks will make them smoother. After replacement, it's recommended to run the ventilation in recirculation mode for ten minutes to dissipate the plastic smell.

I always change the filter on sunny days because the Buick Regal's AC system is particularly vulnerable to moisture. First, remove the glove box: open it, squeeze both side panels simultaneously, and pull downward to detach. Once the beige rectangular filter housing is exposed, press the raised tab on the top cover and slide it left to open. Be cautious as old filters may contain insect remains—wearing a mask is advisable. Avoid cheap off-brand replacement filters; incorrect sizing causes air leaks. During installation, ensure the fibrous side faces outward and gently press along the edges for proper sealing. When reassembling the glove box, listen for three distinct clicks to confirm secure fastening. Don’t forget to label the dashboard with the replacement date for future maintenance tracking.

Replacing the air filter in the LaCrosse mainly involves five steps: It's safer to operate with the passenger door open and the engine off. There are two rubber dampers inside the glove box; rotating them 90 degrees will release them. Press both hands against the inner walls of the glove box and push down simultaneously, allowing the entire box to naturally drop. Use a phone light to locate the filter compartment—the plastic cover's clip is on the right side, and pressing with your thumb will release the old filter. I prefer using a brush to clean out any debris like willow catkins in the compartment before installing the activated carbon filter. When installing, ensure the airflow arrow points toward the seat direction. To reattach the cover, first hook the top part before pressing the bottom, then push the glove box until you hear a click, indicating it's properly reset. A special reminder: replace the filter before the rainy season to prevent odors and mold growth.
