A couple of weeks ago my son tried the A/C system to which we heard a crackling noise. I told him to turn it off, it felt like a bunch of leaves or sticks were being crushed inside the fan. When we got home, there were crushed leaves on the floor indeed.

Dropped the fan/blower and this is what I found.

This is looking towards the evaporator.

This is looking upwards towards the cowl (the external intake to the A/C system)

Could not remove the bottom of the evaporator box for a proper wash, so I have only vacuumed it while blowing the other side with compressed air. Not 100% clean but no obstructions and better yet, no noises. An A/C cleaner spray was used for disinfection and for that "job well done nice smell".
Looking upward.
