I have a 1998 Chevy Cavalier and no matter where I turn my heater knob it always blows out of the same vents. I suspect a vacuum leak but need help as to where to start looking. Is there a particular side of the motor to start on? Any help would be great.
Thanks

Here's the chevy charts for it, It's either the switch, or vacuum, line or acuator leaking.
