Clicking tapping noise coming from behind glovebox

I’ve kinda had this problem before. Same intermittent noise from the rear was a blend door actuator that I replaced. Now I have same noise coming from behind the glovebox. Problem is I can’t locate exactly what part it is. I think it might be the damper on the blower assembly. But how the heck am I supposed to be able to get to it? Do I have to remove the entire blower assembly? I’m trying to do that but there is one screw at the top that comes in from “the other side”. I thought maybe from a bolt from inside the engine compartment but no dice there. Info on the internet seems non existent other than some other actuators that are mounted more towards the center. That’s not the culprit. Any advise greatly appreciated
