Side mirror diagnosis. Got a better hypothesis than mine?

This morning, I started my M3 coupe and hit the button to "untuck" my side mirrors. BOTH of them opened/unfolded past the stop point so that they were pointing straight forwards. I wish I took a pic on my phone because they really looked ridiculous.

I hit the button again and the tucked in properly, and when I hit the button a third time, they both opened/unfolded past the stop point again to point straight forwards. This happened again a few times until the passenger side mirror stopped appropriately, but the driver's side mirror continued to malfunction.

I managed to get the driver's mirror to stop in a usable position by just manually provided some resistance to it as it unfolded at the stop point.

About an hour later, both mirrors were working fine again.

What's your diagnosis?
