Tapping noise coming from passenger side dash. It happens when turning the truck on, off, and when I turn the heat/ac on or off. It lasts for about 5-10 seconds and stops. I have already replaced the recirculation fan/motor.

Let the mouse out.

You've probably got something stuck in one of the blend doors inside the airbox.

Open the airbox and see where the problem is. Here is an exploded view of the airbox and what's in it.
