prior out with a flat screw driver
Fuel level, heat or air conditioning up, both high and low, high only, floor only. Center vents are for air conditioning output only, no heat. Heat is designed to blow out side and floor vents only. NOT center. Center is only for air conditioning or summer vents.
The a/c - heater controller is out...........
You need to look on the passengers side under the dash..........
If you are attempting to remove the center air vents in the dash panel you will need to: 1. Remove the driver side Cigarette Lighter and the Passenger side Auxiliary plug-in. To do this locate the slot at the bottom on the each of these that will allow you to pop it loose with a screw driver. 2. After removing the panels un plug them and set them aside. You will then see 2 screws, remove these. 3. Carefully pry the panel loose. It will pop off but use gentle force so you do not break the panel. The air vents come off with the panel. From there you can remove them or clean them...
Air flow is controlled by plastic doors which are controlled by vacume motors. Could be they're stuck, or a vacume leak.
This is a very common problem and you need to check for a vacuum leak, broken vacuum line or a loose vacuum line......
To remove the air vents on a 2004 Pontiac Grand Am GT, a person will have to pry them out with a screwdriver. Apply gentle pressure between the vent and the dash.
AC VENTS are in the correct position if they are open and free flowing. Some systems have a heat and an AC position for the vents. The AC position is so the cool air discharges from the vents higher on the walls or from the dash rather than floor or windshield in a car.
Replace the cabin filter. remove panel under dash on pass side.
I call it the HVAC (Heating, Ventilation and Air Conditioning) box.
