In the video it seems easy, it seems that it just stretches, but in my case it was impossibleI tried following that video as well and gut stuck at the bottom clips as well. I couldn't get enough clearance to even get a tool/my hands back there to release the clips.
Do you have to release the tabs behind the grill?Once you get one end started, it becomes easier. Start on the left side first. Remember that the bottom tabs must be lifted towards to "let go"
Edit..... Push them down. Then they will pull out
