Can somebody tell me where it is? I pulled the head unit last night and the multi port vacuum switch had fallen apart, so great I thought I found the issue. Replaced it, not hearing any leak but no change in airflow. I found an actuator behind the glove box and cycled it but no change. Found an actuator at the floor at the vent outlet and cycled that one, same thing. I couldn’t get a good look up high in the dash but is there others I am missing?
