2011 LS 460 sport, has anyone had a problem with the AC, set on auto, coming on after the car has set for 20 min or longer. The auto light will come on , but no air. After 20 seconds the auto shuts off. I must then press the auto control and the AC will start as it should.
Try resetting the AC. It worked for me. Push on the off button for a couple seconds until you here a couple beep. Did you replace the cabin filter recently?
Tried resetting the AC. Did not correct the issue. When the auto button light goes off the screen will read fan off. I did replace the cabin filter recently.
