Assuming that the blower motor isn't on fire, it's probably the heater core. Does the smmoke smell sweet. If yes that's antifreeze. The smoke does smell like anti-freeze. Does this suggest that the heater core is the problem?
A smell coming from a reverse cycle air conditioner may be a signal that the filter needs to be cleaned. A smell like engine exhaust might be present if the air conditioner motor is in need of repair.
