Interior clicking noise - 2013 Yukon

[TruckME]

Hi everyone,

today after I started the car, I could hear a very clear clicking noise coming from the right rear side. The noise can only be heard from inside and not outside. My guess was that it is connected to the AC of the car so I turned it off but the clicking remained for the rest of the ride. Not sure what this is to be honest. Any ideas what to be looking at?

Thanks

You out driving around in the fast lane with the blinker on again?

Possibly the blend door actuator behind the rear seat. Had it as an issue on my old 2003 back on the day
