That's a good bet. It would help if you tell us the conditions that blow the
fuse - rolling up, rolling down, both or just sitting there. If it happens
while just sitting there I suspect the short is not in the regulator at all,
since most (all?) models only apply power to one side of the motor, and
ground to the other, while moving the window.

Assuming the fuse only blows when trying to move the window one way or the
other, the answer to the problem is inside the door again. If you had it
done at a shop, take it back. If you did it yourself, time to remove the
panel again. If the fuse blows when the motor is connected and you try to
operate it, but not when the motor is disconnected, there is a short inside
the motor. If the fuse blows even when the motor is disconnected check for
pinched areas in the wiring.

What model and year Acura, BTW?
