Does a 2002 explorer have a cabin air filter? If so, where is it? My ac feels like something is restricting the airflow. I had this same problem on a previous owned suv and after cleaning the cabin filter the ac blew like brand new. My ac blows fine but, the max ac switch is not working. Ac and max ac are putting out the same amount of air flow and max ac used to blow twice as strong. I also have rear ac and it seems to be fine. Any help appreciated.
