So my whole HVAC system works great except the driver side console vent is stuck on. If i have it on floor only, mix floor defrost, or defrost that one console vent stays on. From what I've seen the console vents are all linked aren't they? (haha I guess not if only one is stuck on)

What should I check for? I've looked for obvious leaks in the vacuum line from the ball to the dash and found nothing. What could be causing this vent to stay open?

 

Can anyone at least tell me if there's only one door that opens to let air to the console vents?

 

The center console vent feed is under your HVAC controls. It's an opening and the center console piping fits into that which sends it to the center console vents in the rear passenger area.
