Because it's on fire.
It could be steam from the heater core
White smoke is usually vaporized coolant. You may have a blown gasket or a crack somewhere.
WHERE IS THE SMOKE COMING FROM ?
You may have a slipping fan belt or, more likely, an oil leak into the heater core.
Blue smoke from any car usually means that engine oil is being burnt, either inside the cylinder or on a hot surface such as the exhaust manifold, you need to ckeck for an oil leak, blown gasket etc.
white smoke can be either your car overheating, or smoke from an electrical issue
this kind of thing happens in my durango when i have the ac on and its humid inside the car.
Shampoo the upholstery, carpet and the fabric interior roof, use window cleaner on the windows, use a cleaning solution on the doors and other solid surfaces inside the car. Use a leather cleaner if your seats are leather. If the smoker smoked with the car windows closed and the car reeks of tobacco smoke you cannot rid the car of the stench.
Smoke could be coming from the vents of your car for a number of reasons. You may have an internal car fire.
It probably did not have an oil change in a long, long, time and all that smoke coming out was the sludge left inside burning. Add oil and then drive it to a repair station to change the oil and filter.
