Question
the ac heater blower on my f150 dont bloe any air everething work only that dont blow air i check all the fuses so any body can tell me was the problem

Answer
if the blower isn't working-and fuses are ok  you need to check and see if you have power and ground at the blower when switch is on-if so then you have a bad blower if not you will need to check power from blower switch-if motor runs but no air out the vents then check for vacuum leak in hose going from engine to inside truck on passenger side.
