Steps to replace the air conditioning filter in a LaCrosse are as follows: 1. Pry open the glove box from the side. 2. Unscrew the 3 screws on the upper part and the 2 screws on the lower part of the glove box using a 7mm socket. 3. Pull out the glove box, release several clips, first pull towards the passenger seat direction until the clips loosen or detach, then open the glove box lid, forcefully pull the other side outward to remove the glove box. 4. After securing the wires and air conditioning pipe clips, remove the entire glove box. 5. Once the glove box is removed, the air conditioning filter will be visible. Open the clips on the outer side of the air conditioning filter, then gently pry both sides of the air conditioning filter outward with a small screwdriver to remove it. Pay attention to the markings on the front of the air conditioning filter; the side with text should face outward, and the arrow should point downward. Insert the new air conditioning filter in the same orientation. 6. The installation steps are the reverse of the removal steps; simply reinstall the air conditioning filter in the reverse order.
I think replacing the LaCrosse's cabin air filter can be done in a few steps. When I do it myself, I first clear out any small items in the glove compartment to prevent them from falling in and getting lost. Then, I press the plastic clips on both sides of the glove compartment and push inward firmly, causing the entire glove compartment panel to drop down, revealing the filter housing behind it. Next, I use my fingers to unhook the clips on the filter housing cover. Pulling out the old, black and dirty filter always gives me a shock—it's packed with accumulated dust and pollen. Remember, the airflow direction arrow on the new filter must face downward when inserting it into the slot, otherwise it will affect the air intake efficiency. Finally, when reinstalling the cover and glove compartment, don’t use too much force—Buick’s plastic parts are quite fragile. I replace it every six months, opting for an activated carbon filter to eliminate odors. Buying it myself costs only 30-40 yuan, much cheaper than going to a repair shop.
Last time I changed the cabin air filter, I found the LaCrosse's design quite user-friendly. After emptying the glove box, simply press the raised tabs on both sides and gently pull down to fully open the panel. The black rectangular box behind it is the filter housing—press the clip to lift the cover, and the dirt level on the old filter was shocking. The key when installing the new filter is to ensure the arrow printed on its edge faces the rear of the car; otherwise, filtration efficiency drops. When reassembling, make sure the filter housing cover clicks securely into place, and push the glove box back without letting the panel pinch any wires. If you can't manage it yourself, just visit a repair shop—they'll charge at most a few dozen bucks, which beats breathing dust every day, right?
