AIR SELECTOR

2004 Chevrolet Blazer • 2.3L 6 cylinder 4WD Automatic • 140,000 miles

Air selector switch not working right. It turns but will not shift air to anything but front vents. Blows hot or cold air no problems. Temp control is fine and fan switch also works fine as well. Just the air directional selector dose not redirect air where selector is set.

Check to see if your mode actuator an d other actuators are getting vacuum when dialed to that position they are under dash see pic of mode actuator. Also check for a vacuum leak start at engine.
