Ok, this is going to sound basic, but how in the world to you remove the interior door panels on a 99 ML430? (both front and rear) There are no screws that I can see, nor obvious clips. I would assume it is a situation where you need to give it a bit of a whack from the bottom upwards, but with the door mounted airbags in the front I wanted to ask around before I go blindly jaring the panels.
