It is most likely your heater core. You may also notice a foggy-film on the inside of your front windshield, this is caused by the coolent coming through the vents. The part for this is not that expensive, but the labor is. It is a big job, so shop around good luck. you might be leaking freon THIS IS BAD! it will give you extensive brain damage get it fixed quick and dont run the ac till you do..

How do you know if a diesel engine is burning oil it has been smoking since I had the oil changed the smoke is white but smells like burnt fuel?

The main part of diesel fuel is kerosene, which produces thick black smoke, and gives that smell that is commonly associated with diesel. most likely if it is white smoke, it is antifreeze, if it has a blue tint to it, it is oil. the smell of burnt diesel is rather strong so it could cancel the burnt oil smell, or on the other hand it could be coolant, because burned coolant doesn't have a strong smell. I would check your coolant and oil levels, and check your coolant for having oil in it.
