[cdp3456]

My sun roof is stuck 1/2 open the passenger side seams have something stuck in it. I tried the hand crank on the motor but it is locked up. and I don't want to brake anything you know $$$$ I can get it to move an inch or so. I found a small 10 mm bolt in the side rail on the driver side I can't see were it came from. Is there some were that tells me how to remove the thing? were do I start does the head liner have to come out and how does it.. Is there one cable or 2 cables help help I'm in Michigan and of course we are getting a lot of rain this week.
