Noise/clunk under driver foot well from rear AC
Hey guys,
2017 S63 with rear AC. When the rear AC is on here in Florida, I notice a clunk/bump type sound and movement under the driver floor board sporadically.
Its almost like a gear or flap is engaging. Any ideas what this could be?

I would sit in the car running and acuate the selection between the b pillar and the floor vent and I would also check the floor vents for anything in them. They are at the back and beneath the front seats.
