valve under center dash was stuck.......
have been looking through posts all day when now i have just found a post about the location of the flap valve under center dash.
if u have problems like me check there. from passenger side look under dash toward the center and theres a valve attached to a pull cord. if its pushed out thats your problem. if its pulled shut sorry this couldnt help.
