Welcome to Allpar. Loud, like a vibration may mean that something is in the squirrel-cage blower fan wheel and that the imbalance from spinning is causing the vibration. The cowl screen is supposed to block leaves and debris from entering the blower fan, but sometimes things get through.
The blower resistor may have opened and will only provide high speed if this has happened. Removing the glovebox door might give you easier access to the resistor and blower motor.
