My Toyota Aurion 2009, every time I start the car, my front windscreen defrost button keeps blinking for 30 - 60 seconds. During that time, can’t operate the air cond. Then it becomes normal. There are not much information about this issue but I did check for the air mix and mode selector motor and it moving. But one thing I noticed about the mode selector motor that when I start the car it move back and forward then stop. However, when I select the mode from main to main and floor, to floor, to floor and screen I don't see it move. Have anyone know or experiencing this issue? Hope someone can help. Hope someone can record the movement of the mode selector motor that I can compare with my. Thank you
