Sometimes the moon roof does not open all the way. Sometimes it does. It'll stop half ways at times and sometimes it only opens 1/4 of the way. It is very erratic and there does not seems to be a pattern as to when it is happening. Any ideas?

I see a sunroof motor available at http://www.parts.com/ buts its very expensive and the labor the replace this is 2.2 hrs, maybe try some WD40 first to see if it just needs lubrication.
