I have a 2000 Pontiac Montana and air is barely coming out of the front top air vents. alot of air is coming out of the floor vents. I took out the cabin air filters to check them and there is alot of air circulating in there. I changed the mode to defrost and back and it wont change at all. I am hearing that its the mode actuator that is bad and that is located on the passenger side under the dash. Can anyone tell me where its at or have pics and a thread to go by. My mom is disabled and I want to get the air working again for her. It just did this all of a sudden. Im hoping that its only the actuator motor for the blend door.. please help Thanks
