The obvious thing that springs to mind is the heater core has a leak and the fan is blowing coolant mist into your car. Don't know what else it might be.
Buick heating uncomfortable

When I turn the heater on in my '96 Buick Regal, I start to feel sick and eventually have to turn the heater down or off. There is a smell to it that I cannot identify.
any thoughts?
thanks Nadeem
Is it a sweet smell? If so, the heater core is leaking.
Otherwise, you may have an exhaust leak that is getting into the heater somehow.
Could be a dead animal.

As stated by others, antifreeze, exhaust, dead animals. Could also be mold growing on the A/C evaporator. Many auto accessory stores have a special anti-mold spray you shoot into the heater's fresh air intake to kill the mold.
