Yes, the MBz CD instructions, which are NOT as clear as BOBB's, state to lower the window and pop the top rail out.. THNX gents, panel removed with NO J clips broken, and I'm on my way to R&R the regulator! Hope its as easy.

I found no issue with the door handle. My tip is to use your knee against the bottom of the arm rest and lift as you pull up on the ashtray cutout or other surface. Also DO pop the top rail off a the upper front and work it loose before you attempt to remove the panel. Its TIGHT.

Piece of cake due to these folks here at mercedesshop.com!
