There is not a fuse that controls the air to your vents in your 2000 Toyota. The vents are controlled by blending doors. The doors open and close to direct air to the desired location.
I close the door and vents to rooms I don't use on a daily basis because I don't want to heat rooms I am not in. That can get expensive and it's not "green".
In summer it's desirable to keep odors away and to improve cooling under the unit . In winter I always close my vents halfway.
Yes, especially if you live in an area where the humidity is higher. The vents allow moisture in the air to escape from under your house. Moisture trapped under your house can cause mold and floor rot. The vents should always be open a little. This is to ensure you don't get a sick home and so the air circulates through the house. That's if these are hvac vents. If the vents go to the outside, they should always be closed.
probably an actuator vacuum operated to open/close heat vents
I'm not sure what vents you are talking about, but usually air vents are known to be working if there is air flowing through them.
Usually is a vacuum problem. The vacuum works through the climate controls to make the vent doors open and close.
6 p.m. until it is open for the summer (memorial day) then it is 12 a.m.
Yes, Mt. Erebus does have secondary vents. There are many of them, and they are located close to its inner crater.
