You can use dampers in the grilles to lower air flow...

The dampers I've seen in current window ACs only change direction.

to lower the blower speed when it is humid in the house...

Sounds good, with a $16 motor control, but the motor might hum at low speed,
and most current window ACs use a single motor with 2 fanblades, so this
would also reduce the condenser airflow.

Using duct tape to fix the problem is a bad idea.

Would you prefer an old sock? :-)
