Next, we access the HVAC case behind the glove box to check the cabin filter’s condition and replace it when restricted. A visual inspection of the intake ducting and mass airflow (MAF) sensor area helps catch issues like loose clamps or debris that could affect drivability. We finalize by ensuring proper fit and orientation for both filters and verifying that housings are secured. Ready to plan your visit?
