Not a huge fane of crawling on the ground I was able to change my fan out the top. I think I may have cut into some of the plastic ductwork to make It possible.

I do recall some of the bumper cover screws were rustes into the spring nuts and just spun the nut you can't access. I used a small hole saw to cut the plastic around the nut and used a larger head screw on reassembly.

I live in the rust belt your experience may be much less rusty.
