Air not blowing out of vents in car?

Fan not working or you would feel cool air if heater door was working. Can you hear the fan?

It could be that; the FAN MOTOR works but the fan-wheel is not turning. This usually happens when the center spindle of the fan-wheel RUSTS and eventually loses contact with the actual wheel itself.

Most vehicles today have what is called a blend door and motor in the heater box. The blend door motor comes on when you select a setting. It actuates the blend door and directs the floe of air to the proper place. Sometimes the blend door gets stuck from debris that falls down through the vents. Also it is possible that the blend door motor is bad or simply came unplugged. Some of these motors are powered by electric automotive current and some are powered by vacum hoses. It is possible for the vacum hoses to break or become unplugged. Check all these options. One of my kids dropped a comb down my upper vent and it blocked the blend door from directing the air flow. That was an easy fix and I hope yours is a simple. I hope this helped you. Roger

had this trouble in a dakota it was a blend door in the heater unit. had to remove entire dash to repair

From what I hear it is a vacuum line issue. Mine is doing the exact same thing. So, I am going to get a diagram and try checking the vacuum lines to see if any are loose or tore

I go under the dash and feel the air flowing out the floor and it is coming out of the defrost, also. I noticed under the drivers side today that air is flowing and there seems to be a gap in between a part under there. There was some material stuff I saw around the edge of it that sticky brown stuff and it sometimes before came out my vents all the time. Anyways, not sure if my air is just not sealed good to blow out the vents but it is something that happened not long ago and we've not done anything under our dash area.
