Blower motor functioning ok but air only coming from defrost vent no matter what setting is on. Is there an electric motor that operates the ducts? Anyone had this problem? It's a 90' model.
 
check just under the glove box. someone probable kicked your vacume line off. I had the same problem when I got my car.
 
yep, happens all the time. You're looking for a small vac line connected to a round actuator looking thing righ above where the passenger feet go.
 
Had the same problem. It turned out to be a crack in the plastic vacuum line under the hood. It is hooked up on the pass. side in the back by the fire wall. There are two other line hooked to the same place. One of those three lines goes throughthe fire wall and controls the heater/ac stuff. That is the one you need to look at. Just trace it out. I'm sure you can find where the problem is.
 
I'm a dumbass, didn't have the car running. Finished repairs fired it up, vents work fine. Thanks guys!:eek:
