I have checked user manual for my Hybrid and there is no mention of door mirror, except "heated door mirror".
I would suggest to you to check all fuses which you are not sure what is their exact purpose.
Saying that, in previous generation power mirror shared fuse with AC clutch and some other devices, so fuse labels may not be enough to find correct fuse.
I am not car electric expert, so this is just an idea.
Because both mirrors use the same switch, and especially if all other electric works as it should, I very doubt that the problem is with fuse.
It looks like loose contact somewhere or failed electric motor in the mirror.
