Vacuum and ac control

Any thoughts on what to check when I can't adjust airflow(hot or cold) by turning the control. The air only comes out at window...

No problem here. Just go to the top of this page and click on FAQ and then type in what you are looking for.

Jterr- the air is directed to the defrost, dash or floor by vacuum cylinders. If things dont change, you probalby do not have good vacuum. Normally you wil end up with defrost only when you loose vacuum. Read the related posts and look for vacuum leaks under the hood on the small vacuum hoses in front of glove box and motor at the firewall.
