I cannot see a PA-28 trimmer when I am in the seat either. So I exercise it by reaching inside whilst in a position where I CAN see that it is working, symettrical etc. Same goes for anything on any other plane where I cannot see it from the seat and play with it at the same time.
Oh and I always check the "sense" of travel as well as for full unimpeded travel, as I do for the elevators and ailerons.
Since I once found an aeroplane with almost no fuel on one side and half a tank on the other .. I have decided to treat any aeroplane is if it has been last used by somebody trying to catch me out or do me in.
