I have seen this with seldom used air impact wrenches. The air paddles in
the motor get stuck in their slots and will not seal. You will hear the air
escaping from the wrench, but with little movement or power.
You could try to squirt some air tool oil in it, spin it just a little to
spread it around the paddles, let it set for a few hours and try it again
to see if it free the paddles before you open it up.
best,
