hi, its me again with another question, the air only comes out of the defroster vents and floor vents. What causes this? how can I fix this. Its annoying, and frustrating because ive looked at everything i can think of to fix it. Any and ALL help is greatly appreciated thanks[sm=smiley17.gif]

 

Sounds like vacuum problems. There is a vacuum harness with about 6 or 7 lines under the dash that has a connector that crumbles with age. One the lines goes through the firewall to the manifold that supplies vacuum for the controls. The connector is on the right side of the steering column.
