2002 Jaguar X-Type Cigarette Smoke

I recently purchased a 2002 Jaguar x-type for my wife. It appears that the previous owner smoke in the vehicle leaving a strong odor of cigarette smoke inside the vehicle. After cleaning it multiple times, the smoke disappeared. Now, when the a/c comes on, there is a strong odor of cigarette emitting from the vents; it smells like an ashtray. How can I remove that odor?
