1-2 minutes after starting the AC, the air from the center air vent gradually stops blowing and redirects to the windshield vent. This happens when I first start the engine. What can cause the fopper to close? is is vacuum hose leak or is air solenoid probelm???

Hi, did you find out why this was happening? I've seen this due to a vacuum leak, especially from the vacuum dampers, but that was on another type of vehicle.
