3 Answers
Cadillac ATS cabin air filter replacement steps are as follows: 1. First, remove the clips located at the front of the passenger side in the engine compartment, then take out the sound insulation cotton. Be careful not to damage the clips. 2. After removing the sound insulation cotton, reach inside to take out the cover plate, then reach in again to remove the cabin air filter. 3. Install the new filter. Note that there is an arrow indicator on the outer side of the filter—ensure it is not installed backward. Cabin air filter cleaning tip: If the filter is dirty, clean it by blowing compressed air from the reverse side. Hold the air gun about 5cm (centimeters) away from the filter and blow at a pressure of 500kPa (5.0 kgf/cm²) for approximately 2 minutes.
I've been driving my ATS for several years, and changing the air conditioning filter is a pretty straightforward job—it's located behind the glove compartment on the passenger side. First, you'll need to empty the glove box of any items, then gently open the glove box lid. Take a close look at both sides, where there are usually a few clips or screws. Press them lightly with your fingers or loosen them with a small screwdriver. Be careful not to use too much force to avoid damaging the plastic parts. When removing the old filter, pay attention to its orientation. When installing the new one, align it according to the arrow indicator to avoid putting it in backward, as this could reduce air filtration efficiency and even cause odors. The whole process requires no additional tools and takes about 10 minutes. Regularly replacing the filter is crucial—typically every 10,000 to 20,000 kilometers or once a year. This improves cabin air quality, reduces dust and pollen, and makes the air noticeably fresher and more comfortable when using the AC. I recommend using OEM or reputable brand filters to avoid subpar filtration from off-brand products.
The first time I changed the cabin air filter for my Cadillac ATS, I was a bit flustered, but it became super easy with my friend's guidance. First, sit in the passenger seat and open the glove compartment to its maximum angle. Then, look for clips or small screws at the bottom or side of the compartment—press them with your fingers or gently turn them with small pliers to release. Next, carefully pull out the filter housing, remove the old filter, and observe the airflow direction indicator. When inserting the new filter, make sure the arrow points toward the front of the car. Installing it incorrectly can lead to poor airflow or even strange noises. After replacement, simply snap the glove compartment back in place and test the airflow to ensure it's normal. Beginners might worry about damaging parts, but the materials are quite durable—just avoid pulling too hard. It's best to replace the filter every 12 to 24 months, especially during spring when pollen is abundant, to prevent sneezing or stuffy odors in the car. Buying the filter online is cheap, and DIY saves both money and time.
