Air is not blowing out of my front dash vents regardless of whether the a/c is on or off. The back vents in the middle row of the car work fine. And if any air does decide to come on, it is barely coming out even if you have the fan set on full blast. Help, please!

The mode blend door actuator is used to send the air to specific vents. The actuators fail frequently and on this model they have updated the actuator to a revised style because they have had a lot of problems with them. Here is the location of the actuator in question. Check out the images (below). Let us know how it goes

Is this the device that is located behind the glove box? How much do these items usually cost? My boyfriend will be able to fix it for me. I want to get the problem fixed at the lowest cost to me.

It's not behind the glove box. It's on the other end of the housing to the left of the radio. You can see it looking up from the driver's side.
