Cabin Air Filter Replacement
All Buick & GMC makes, models, and years were designed with a cabin air filter that removes particulates from the air before it comes through the ventilation system into the cabin. Without a fresh, clean cabin air filter, you might be breathing in polluted air. The cabin air filter is usually located under the dashboard behind the glove compartment on most vehicles but having a certified technician is always the best option. The cabin air filter will eventually wear out and fail contingent upon various conditions such as driving on unpaved roads
