What is this Clicking Noise behind glovebox

Toyota Tacoma 2006 2 cabin.
I started the car up and heard clicking behind the glovebox. I know not all cars are the same so feel free to ask questions.

Very likely there is an electric actuator for the HVAC system that is broken. The clicking is a stripped gear as the motor keeps turning. It is under the dash. They aren’t usually expensive to buy, but sometimes can be headache to replace.



A broken activator will click when changing the temp setting as it tries to move the blend door. Directly behind the glove box is the fan. The cabin filter is supposed to keep debris out of the fan, but something like a leaf stem touching the fan can also cause a tapping sound that is faster with increased fan speed.
