You will have to hold down these two buttons for about 5-10 seconds, or rather until the LED lights of both buttons start flashing. The lights will start flashing to let you know you have held the bottoms long enough.

After this, wait for another 60 seconds, before you switch on the Engine of the car to allow the AC reset to reach completion. Your AC should be back and running normally.
