1. A method for operating a vehicular HVAC system, comprising:

  • determining at least one of;

    a vehicle tilt angle; and

    a condensation value;

    detecting an elevated risk of water splash expulsion from an evaporator through a vent outlet based on at least one of the vehicle tilt angle and the condensation value, wherein the detection of the elevated risk of water splash expulsion from the evaporator through the vent outlet is made using a controller that receives the vehicle tilt angle and the condensation value as inputs, and detects the elevated risk of water splash expulsion from the evaporator through the vent outlet based on at least one of the vehicle tilt angle and the condensation value; and

    controlling a voltage supplied to at least one blower of the vehicular HVAC system to reduce a risk of water splash from the evaporator through the vent outlet if the elevated risk is detected, wherein the voltage supplied to the at least one blower is controlled using a voltage controller configured to control a voltage supplied to the at least one blower of the vehicular HVAC system.
