Re: Air vent problem.Help!
Check the condition of the vacuum lines at the selector switch (pull the dash faceplate off, and from there its 2-4 screws..) That's a good place to start... I don't have a vacuum diagram with me but if you pull the connector out for the vacuum lines, you should have a black one with vacuum when the engine's on...... it could just be a switch...
While your in there see what you can see, listen around for any vacuum leaks... check the vacuum lines under the hood
