== == Could possibly be a heater core leak. Coolant is getting blown up through the vents when you have the heater on. May need to do a heater core check and replace. if you have the a A C on it means that your A C freon its leaking, also if you run the AC on with one window open it will create smoke fron the humidity coming in to the car if it's white somke it's dangerous "cause it will put you to sleep while you drive and you will not feel it..
