Dash Vents

For some reason the air will not blow threw my center vents. Is there a motor that moves the vents when you move the lever?

If you have an A/C car, the air will only blow thru the center vents with the A/C on. In the 'vent' mode, it will only blow thru the side vents, and the blower mtr. has no effect on it. If there is a problem in one of these modes, you probably have a vaccuum problem, or a vac. canister may be going bad.

But during the winter I would put the fan on high and lever on Htr and hot air would blow threw the center vents and the right and left vents on the dash. I do have AC.

Hmmm....   I have an '82 with A/C.   Place my levers to vent and all air flows through the sides and center.   Place levers to A/C(max and min) flows through both as well.  Place levers to defrost flows on top, and heat only the bottoms work.

To your question on a motor.  I don't here one when I move my levers from one position to the next.  I do here the air flow through the console when each door closes shut.

OK.......this would indicate a problem in the vac. system, or one of the 'mode' doors that control the airflow. You shouldn't have hot air out of the vents in 'heat' mode, only the floor. In 'bi-lev', you would, but not on 'heat' only. Sounds like it isn't changing the doors properly from one 'mode' to the other. Could be a mix-up in the way the vac. lines are run to the vac. 'servos', or an internal leak at the switch itself.

It's possible that the redesign of the center console area in '77 also changed the way the 'vent' system works. I'm quite sure the earlier models worked the way I described. Sorry for any confusion

Hey, Thanks for taking the time to help out. I hope to get to a point where I can help other people.

ossw1,
Did you get your vents straightened out yet?
Just curious.
