Backup Camera problem - 640GC 2015

[jsahyoun]

Hi all, need some help to figure this out, my backup Camera occasionally moves up and down slightly after engaging , I can see the image goes up and down for few times then stays in position. I am not sure if the motor assembly went bad or requires calibration. I sure appreciate any thoughts or if anyone had similar issues. Also if you have any DYI steps to remove it, that will be great. Thanks
