I see some white smoke or maybe frosting coming out of the left centre AC vent of my Grande Punto Emotion. The car has done just 2800 Kms till date, this started happening some few days back. It happens when i keep the blower on 1 and the temperature on the minimum of the knob. when i turn the knob slighty above the minimum or increase the blower speed, this disappears. Can anyone tell me why is this happening? Is this a serious isssue? Can i continue driving with such an issue?
