trip gauge, no workie...

Hi Everyone,

About a week ago I was filling up at my local gas station. After paying my bill,
I went to reset my trip guage and it didn't fully reset. I pressed again and
it didn't move at all. I tried doing a seach for this, but I didn't find anything.

Does anyone have any insight on how to repair this (if it is serviceable) or
is a new part inevitable?

thanks for you help,
