Disconnect the linkage from the motor.
You should have done this before trying to test motor to insure that the step is not bound up!
I would have, but I’m not sure how to access the cotter pin since the steps are retracted?
Remove the mounting screws from the motor ass'y and drop it down.
This should allow some movement of the steps and help you with removing the cotter pin from the actuating arm.
Once removed, set it on your desk and match it up with a power window unit from Amazon. This should save you some bucks above, going with a step motor, which is exactly the same and what they use.
