I just picked up a 03 SS Enthusiast with nav. The when you press the button to open the cover lid. it opens like half way and gets stuck sometimes like it is out of alignment or not lubricated. Anyone have this problem? and how can I fix it. Thanks in advance.

 

I havent seen how the 03s work, but a somewhat similar thing has happened to some of our 05s...
