This just started (actually about the same time my high beams quit working).  The front a/c system will randomly stop blowing cold air through from vents.  You can hear the a/c running, turn up speed, turn on/off etc.  Then randomly it will just start working again.  Very frustrating because we have to turn 2nd row a/c on high to cool the front of the car.
