Side view mirrors

I tried to adjust my electric side view mirrors last night and both passenger and drivers side does not work.
Where should I start to look for the problem??
looks like it does not have it's own fuse, and everything else works.
I have a 2008 Tacoma double cab
Thanks

Have you operated the left or right mirror selector switch first?

 

Had the truck for seven years, all of a sudden stopped working.
I guess the other day I tried the drivers side one first, then the passengers.
Don't get your question.

 

Look behind the dash to make sure the switch connector isn't loose.

Also, on my '05, sometimes the selector switch gets stuck (it physically "clicks" into place, but doesn't actually switch the mirror); when it does this, I just click it on and off a few times with a little force and it usually comes back. Maybe this happened to yours in the middle position?

 

I think the mirror adjustment is run on the ACC fuse which is in the cab behind the coin tray to the left of the steering wheel. That said if it was a blown fuse you would have other things down like your stereo.
