Odometer, Trip Meter, Speedometer, OH NO!

[Elijafir]

Okay.. so the discussion about speedometers and odometers in the headwind thread got me paying a lot more attention to my gauges.  And wouldn't you know it.. I noticed it catching just a little bit every time it rolled from .9 to .0.  The worst I noticed it was "stuck" for a mile.  The Trip meter and Speedometer are still working like usual, which weirds me out.  And then on my way home this happened:


AND I'M TOTALLY LIKE WTF ABOUT IT!!!
It was stuck like this for 5 or 10 miles!! and is still stuck.
It's very weird to me because the Trip meter and Speedometer still work NORMAL.  
How hard is it to open them up and fix this?  Is it even possible?  I don't even see how to open them?  I've had it out to change the bulb, etc.. So I know how to get that far.  Please help!!  Thanks.

I have seen this before, take the clock out and gently tap it face down on a hard surface few times with the aim of freeing the mechanism up. It worked for me, might work for you
