FanTastic bathroom fan?? ((UPDATE)){{{UPDATE}}}}

Have a bathroom fanTastic fan which has a 12v motor on it like this...

Fan Tastic Fan

I replaced the motor lift assembly about 3 months ago and fan worked fine opening and closing cover after flipping the switch... about 2 weeks ago I went to open the vent and the motor turned the knob about 3 turns and the vent opened about a inch or so and stopped. I had to turn the knob manually to open vent and have fan turn on. when I flipped the switch to close it nothing happened. Had to be closed manually... Same thing happens every time I go to use the fan...
I have 12 volts to the motor and thats about all I checked. Any suggestions as to what else could be wrong or what to check for?? I don't see any obstructions or anything in the way. The trailer is in the same location when the motor worked and when it stopped.
Thanks for any help.

    There is a cutout switch that turns off the fan when the cover is closed.
    That switch goes bad sometimes.
    It may or may not have something to do with your problem.
    It is a pin that gets pressed down by the cover when it is lowered. Fairly easy to bypass temporarily for testing purposes.
    But tbh your description sounds more like an overload issue with the lift motor. Have you tried to grease the lift assembly? Or maybe something has become unaligned, a screw turned loose or something, and now the motor does not have enough power after the first turns? If that is the reason, and you crank it up further manually, I would expect the motor to not be able to crank it down either.
