Magma or lava vents and gas vents. Also fumarole.
Yes. It probably did. Mostvolcanoes have vents. They let more lava escape.
Vents in the volcano are passage ways for the magma, steam, and heat to escape the earth.
The magma gushes out and then it flows every where. The volcano has vents that let air come out. When the vents open steam/ smoke comes out of those vents.
Yes, Mt. Erebus does have secondary vents. There are many of them, and they are located close to its inner crater.
Not really! The actuator is there to control the airflow through the vents.
Do you mean for directing airflow to the different vents?
It is Likely a vacuum leak under dash leading to vents
Not really, there's not much airflow when the furnace is not running.
Airflow improperly set (too high) or the most common undersized ducts.
A shingled roof requires ventilation. That can be done several ways. Gable vents, turbine vents, air hawks or ridge vent. It is also important that your soffits are vented to get proper airflow.
Mode switch is for the climate control. It allows you to direct the airflow from your feet, to the dash vents, defrost etc.
Make sure you have vacuum going into the cab from the intake manifold. (If you do and still no air, the problem is in the controler.
air may not be getting directed to your vents, this happend with mine, its usually just a vaccum line that seems to every now and then just fall off....check under your hood for a vaccum like just hanging there and hook it back up. This should solve your problem
Diagnosing this problem depends heavily on the year, make, and model of your vehicle. Some older cars use vacuum powered doors inside the vent to control airflow output location, so there maybe a vacuum leak to the center door. Almost all cars have handles on the vent outlet grill that manually directs airflow from side to side, and can completely block the vent if needed, so the center vents maybe be closed. Newer cars use temperature sensors, mounted under the dashboard and inside the vents that can control airflow, so the temp sensor maybe out of range. In vehicles that have sat for long periods of time, or are seldom used, rodents build nests inside the vents and block the airflow, so there maybe an animal nest in the vent. Without knowing the specifics of your car, my only advise can be to have a mechanic professionally diagnose your vehicle.
types of airflow, functions of airflow, properties of airflow,
It should blow through the floor vents. Modern vehicles generally use movable baffles in there HVAC systems, to direct air flow where the controls indicate. If the controls allow airflow to the floor, but nothing flows out, there is a malfunction between the control switch and the actuator that directs the flow.
