I'm redoing my entire center column. Rebuilt my AC mode switch. Putting it back together. Did a test to see if the mode switch is working right, but it does not move to the vents still.
When I had it all apart, I pushed the flap inside the center vents and it just bounces freely. no resistance at all.
Upon further inspection, I notice on the right side, there is an arm that comes out. With a white plastic bent arm on it. with a hole. But not connected to anything. Looks like there is a device up farther that is suppose to be connected to this arm. the arm moves the center flap open and close. Anyone have a close up on how the little arm connects to whatever that is in the housing in back of it? i'm thinking on just taping it up for now so it's always on vent. which is what i'll be using 99% of the time anyway.
