You most likely have a vacuum leak not allowing the vacuum operated vent/duct inside your instrument panel to operate. Check all of your rubber vacuum hoses in the engine compartment for leaks, cracks or breaks .

Your climate control switch is not working correctly,so it won't allow it to switch to blow out the vents

if both vents are blowing air in general then you may need to get your air conditioner recharged, but if the front vents aren't blowing at all then you may just have a jammed vent flap and you can fix that from under the hood next to the blower motor. check you rowners maual for the exact location

Cold Air Not Blowing Through Vents


Your last guess is probably the right one. The deflectors/directors are vacuum controlled and you may have vacuum line either broken or disconnected; these aren't fun to find. I would start under the hood and make sure the vacuum reservoir is intact (have seen them cracked) and then start tracing hoses from there.
