Stuck Seatbelt

I have a 99 Sienna XLE. Seatbelt on the second row passenger side is stuck. It only opens little bit and then stops. It appears something it stopping it from being release.

Is there a way to open the side panel to find out what is stopping it? Does the side panels pop out or there is another way to take them out?

Download and read the relevant portion of the Sienna FSB linked to in the sticky post at the top of this forum.

I pick the symbol thought to be as confusing as I was about my problem with stuck seatbelt. If it has offended any one, I am really sorry.

Does anyone know how to remove the side panel near the center passenger side seats? Need to remove it to have a look at the stuck seat belt. I have the repair manual but it does not show how to remove the panel.
