Dunno if something got in there, or what.
A good shot of lithium quiets it for a while but it always comes back.
Would like to see if there is something like a little hunk of rock jammed in there if possible.
If just the chrome cover is removed [tips please] will that let you get at the drive for the thing, or is this going to be enough of a pain I should let a dealer take a look.
Chrome cover won't let you see anything. It is very easy to pop the mirror glass off and have a look at it. The actual power fold function is housed within the pivot and you won't be able to get to. Funny thing is my 2011 Avalanche is doing the same thing. It chatters folding in and out. Mirrors are completely different.
Anywho, reference my instructions below on how to get at the mirror internals. I would just do some simple investigation to see if there is something trapped between the upper and lower. If you can't find anything there might be a gear stripped out in the power folding drivetrain.
