Pop-Up Screen Motor

Hello,

I have a 2012 Sedan and the screen is getting stuck and stuck more often. I am suspecting that the motor is going out on my system. I have searched just buying the motor to replace it, but have had no luck. How is everyone refurbishing these? Is there an option to just by a whole new unit? I looked around before opening this post and could not find anything other than used screens for sale on ebay.

Thanks in advance.
