Blower Wheel Rounded Out?

I think the blower wheel has rounded out, but I’m not sure how to get to it without damaging the cover - through the front? top? I saw a picture of someone with the lid up an inch or so, and there was something like a putty knife used to open it. Do I use brute force or is there a clip or something I must unhook first?
