AC won't save the previous setting and takes about 30 sec to turn on(only auto light is on and cant turn it on till the time has passed)

What is your question?

As soon as you start the car, AUTO light would come on but no lights on recirc/auto/fresh air button. And the fan would not run and no driver/passenger temp display either. Looked like the whole climate control system was in a shutdown mode. After 15 seconds or so, climate control would come on rested to 75 degrees and would forget my previous settings when I shutdown the car after a couple of minutes the same thing happens every time. Plus i noticed that the vent door in the glove box is down when i start the car and as soon as the 15 seconds or so has passed the vent opens and go up and the ac system is back functioning. hope someone can help me and thank you very much!
