How come my air wont blow very hard out the vents,you can hear it but not feel it?

If it's the original blower motor it could be pretty tired or you could have a clogged cabin filter. Those would be the first two places I would look.

Check to see if the air is coming out the floor vents or the defrost vents. Could have a problem with the mode actuator.

if your hear it.. the obviously a blockage or something not opening.. there has to be something in between the fan itself and the vents..

Also i dont bilieve those yr and model trucks have cabin filters.
