Stan, Does this mean that the 91 has a ventilation (fresh air) function working from the timer on the OBC? I am still learning this car forever it seems, and on Hot or Warm days it would be nice to have a ventilation availability other than using the A/C Heater controls. The only way I know to ventilate now is to open a window, sunroof or turn on the A/C low. Is there another way? Kurt
