air blows but only out of the defrost vents not below,dash or back seat area.

sometimes when you disconnect your battery especially on newer vehicles it tends to make you computer go haywire. take it to get checked (computer). it may have to be reprogrammed in order make vent controls to work again. sounds wrong but believe me even disconnecting your battery can sometimes cuase your key to malfunction if it has a chip in it. and sometimes reprogramming computer helps with that or simply reprogramming your key chip. so it is very possible this can fix ac vent problems. email or call for further assistance. charlyboy_979@yahoo.com 336-712-5285 sam...
