The air conditioner evaporator drain tube only allows for the draining of the condensation of the water that accumulates on the outside of the evaporator core, so it would not make any difference on anything in the ducts.
Does it also have a bad smell when the heater is on or just the vents, without the ac on?
Does it make a difference between just plain ac and max ac, cause on max ac it shuts off the inlet door and recirculates the air just from the inside.
