Unfortunately, it’s that simple. A ring slid off my finger this morning and right up to the bottom of the front windshield, then slipped down into those vents… Is there any way to access/recover this ring? Is that ring going to be screwing anything up in there?
Yeah, the Car Care Nut on YouTube has a video of a teardown of the entire dashboard assembly to get at something dropped down into the vent system that got into the diverter assembly. It was an involved, complicated process. SM-S936U ?
Probably worth a shot with a video endoscope to locate it, and then possibly extract it with a flexible claw tool. Both of these tools are pretty cheap these days.
