Hi. A horrid smell is usually do to a mouse getting into the heater box. Have you checked around your car and under the hood for signs of mice?
Ok. If you smell a musty type smell that could be from water not draining out of the heater box. But if the smell is like something has died then you probably have a mouse in the box. You can remove the blower motor for a view into the heater box and check for debris.
Yes. Air travels the same way except either through the heater core for heat, or evaporator for ac.
I understand. I hope it gets resolved for you as well.
