Disconnect both air struts from the door. Lift the door up as high as it will go being careful as the lip that holds it in place (essentially the hinge) might release the door allowing the door to fall. If it doesn't fall out of the hinge you will likely have to remove two plastic retainers that keep the door from moving fore and aft and also keep the lip of the hinge engaged. I found these little plastic retainer strips (about 1.25 inches long) were held in place with one, fine, difficult to remove Phillips screw.
I wish I had a photo. It's not difficult when you're at it, just hard to explain.
Good luck. Get back to me if my instructions are not sufficiently clear.
