1998 Accord Power sunroof does not close only open

SOURCE: 1998 Honda Accord Sunroof wont close all the way

I took mine in expecting to have it repaired and it turns out that it was just the screws along the left and right-hand side of the panel.  They were loose.  The guy told me that "it eventually happens" and that "it's only a matter of time".  He went on to say that "it shouldn't happen again".  So, check the screws on either side of the panel right where it's stopping.  I suspect that this is prohibiting yours from closing as well.

HTH!
