Replace evap fan motor

I want to replace the evaporator motor (GE Part WR60X10300) in my GE Bottom Freezer.

My question is: how do I access this part? I don’t know the steps to get to part even though I have a schematic. I have removed doors but do not see screws or tabs to remove the plastic covers.

Any help would be appreciated.

Use steps one through eight from the attached instructions.

Gene.
