From the bottom, unless there's a fan ... in which case it flows in from behind the fan.

It makes to much noise at night
in the heater box. where is box.? under dash. where there.? the part that makes noise with the fan on. IF car has A/C the right side is A/C and left is heater.
the fan could be obstructed or the fan motor could be going bad. I've seen more than once where rodents have made homes out of fan boxes.
Probably the heater blower motor.
When there are loose parts in the fan that runs the heater system, there will be many instances of noise and vibration. A technician should dismantle the system and fix it.
Change the blower fan speeds to see if the noise changes. It is possible that the fan is still running while the heat is off, and the fan is rubbing.
was there something on your dash that fell in the vent, a bad fan will make noise all the time.
when i turn on the ac in my 2000 honda civic it makes a loud noise when the fan is working what could that be ?
The DeLonghi DFH255OTB Safe Heat Fan Heater is a safe option
your engine is loud because, the fan makes that noise
That'll be an airlock, bleed the heater and it will go way
A faulty fan clutch.
