On my 2000 LS the sunroof is now stuck in a semi-closed position. The rear of the glass panel is tilted slightly upward, creating air entry and noise at highway speeds. I was going to take a look at the mechanics of the unit but the interior trim sliding panel is stuck closed and will not slide back. Anyone know a way to get this panel to slide back so I can assess the situation? Hope I do not have to force it. Also, Is there a method to seal this gap until a permanent fix can be budgeted in?
