HVAC air not blowing through the vents properly

This could be a number of issues so we need to start eliminating them. First we need to check each position, the floor, vents, and defrost and see if the air is coming out of any vents. If not, do you feel the air when the vehicle is moving or can you feel this small amount of air at any time?

Here is a guide that will help with this:

Then we need to find out if the blower is actually putting out any air or if there is an obstruction or some other issue with it. You do it by putting 12 volts to the fan which will put it on high and you should be able to ensure it is operating properly.

Below is the info from the manual that will help with this.

Let's run through the guide for this issue and test the blower and then let us know what you find. Thanks
