AC blower clipping
Been having non stop problems with my Z; latest is the AC. When the fan turns on (or when I turn it on), it is audibly hitting/clipping something. It sounds like it is coming from the vent under the windshield.
Seems that this problem is almost unheard of and could only find people with intermittent fan issues.
Got my windshield replaced recently and was thinking maybe something fell into the AC system while the windshield was off?
What are my options? I imagine the fan is not easy to access and don’t want my dash ripped apart.

If it is that easy, you do not have much to lose to check it out. Good luck - hope it is something simple.

Does it sound like a failing "blend door actuator" ... https://youtube.com/shorts/lIr-5zVEJwI?feature=share
Can you create a video of the sound?

Mine has made kind of THUNK sound for several years now. Usually only at startup. It's nothing at all like the youtube above....it's more of just a couple of small thunk sounds and then it's done. Now - when I had the coolant drained down and refilled - it took it a while (maybe 15 miles or so ) before it started sounding normal. I think it was just refilling the heater core.
