Air vents change flow while driving
I have an 02 ram 2500 4x4 that changes the air flow from the middle vents to defrost under acceleration. when I let off the throttle it goes back to the middle vents. this would suggest that the doors are controlled by vacuum. but my haines manual does not cover this. any Ideas?
