[Does my blower motor look normal?]

Above the blower motor is that grid-like space (it’s a bit dark), and it’s open to the inside. Is it supposed to be open or is something supposed to be covering it up?

I’m trying to identify where my air flow is disappearing to. There’s a small gap where the blower attaches to the housing, and a little air is coming out there. Also the left servo motor is not working, no movement when I change air directions on the A/C unit, though right servo seems to work fine—would that make a difference? Heater core has been bypassed, if that makes any difference. The temp itself is cold, just very weak airflow even at full flow, despite a strong blower motor.
