My 94 Grand Am, Dual Quad has lost it's ability to change which heater vent to use, it just stays on the default vents. I assume it's just a vacuum connection somewhere. But where can I investigate this? Anyone else fix this kind of issue? Where can I look for the vacuum connections?
Thanks in advance. DM
The airflow position door is just to the right of the console. The cover under the right side of the dash needs to be removed. Remove hose from vac motor and cycle position switch to see if there is vac at the motor.
