I would test the switch first. It works like a standard home light switch if you know what I mean. A ohm meter will do for the test if you remove the motor there should be two wires coming from it one is for clockwise movement and the other is for counterclockwise. in other words foward and reverse or open and close you can bench test this motor by just connect the positive wire to a battery charger or a battery.
the ground is the motors body
I use a vise for testing motors of all kinds so the motor will not jump off the table, this one is small so no need if you feel comfortable about it
if the motor is good it will work in both directions
