In this video, I show how to remove and replace the cabin air filter in a 2021 Chevrolet Blazer. The ACDelco part number is CF185. I chose to use a FRAM cabin air filter and that part number is FSC11966 and it fit perfectly. Remember to change your cabin air filter about every 15,000 miles or sooner if driving in dusty conditions.
