I need to take the driver door panel off because the window motor is slipping and window operation is intermittant. WHAT A PAIN IN THE A$$. I have removed everything from the light on the bottom, the bolt on the door grip, the side mirror screw, the door lock button, the plastic trim around both seat switch and chrome door handle. The thing won't budge. There is a black plastic piece behind the chrome door handle that has an outer lip at the top and the bottom that curves around the edges of door panel itself. I have tried the "push up on the door panel" method and the thing won't move. Does the inner black plastic piece behind the chrome door handle need to come out?

Thanks
