My sun roof want close all the way. Gets almost there then opens back up

Hello, sounds like there may be a restriction in the moon roof track that is causing the glass to re-open as a normal defense mechanism to protect the motor, track and glass from damage. Have the sliding glass inspected for free movement in the track, clear any debris, and look for damaged or bent components, or binding parts. I'd definitely recommend a specialist who works on roofs have a look; see if you can find one local to you.
