Is there a way to turn on the fan without using the AC (or the heater) ?
It's been so cool (and wet!) here in Ohio that even the AC in the house remains off.
Just make sure the light on the TEMP knob is not illuminated. Press the button at the bottom center of the TEMP knob to turn the light on or off. If the light is lit, the car will try to adjust the car's cabin temperature to the desired temperature. The desired preset temperature is set by rotating the TEMP knob CCW or CW depending if you want higher or lower temperatures. The preset temperature will be displayed in the upper left corner of the screen in the center of the dash.
