why cant i get the blower to blow air out of my vents in dash

on older models your vent duct connections can possibly vibrate themselves loose. you can also check to see if your vent controls are opening and or switching to desired setting. turn on blower and check if you are getting air under dash, if you are while knob is set to dash vents then your ducts have disconnected. email or call for further assistance. charlyboy_979@yahoo.com 336-712-5285 sam...
