Hi there, is this smoke or more like fog, does it disappear, smoke will have a smell and hang around, this may be moisture on the A/C evaporator, the drain tube may need cleaning, if it is only there when you first start the A/C it will be moisture, check this sot and let me know if you feel that this is the problem.
