I have checked the shop manuals that I have & cannot find a breakout image as to how to remove the plastic housing? I know there are a couple of screws to the left of the cover but are there other behind the hush cover.

 

I had the same problem, I was worried about breaking it and couldn't find a good picture. There's the row across the bottom, none of them are very hidden. Then it just pops loose. There's a few tabs at the top center, but they don't snap, otherwise it's just gently pry and pray.

 

Tkx. Will give it a try tomorrow.
