Vehicle HVAC water splash prevention method and apparatus

A controller for controlling operation of a vehicle HVAC system, comprising:

• a vehicle tilt angle sensor configured to sense a vehicle tilt angle;
• a condensation sensor configured to sense a condensation value associated with a condensation risk;
• and
• a voltage controller controlling a voltage supplied to at least one blower of the vehicle HVAC system if the sensed vehicle tilt angle and the condensation value exceed respective threshold values set therefore.

In an integrated front and rear vehicle HVAC system comprising a rear evaporator disposed between a rear blower fan and at least one rear vent outlet, a front blower for a front portion of the HVAC system, and a controller, the controller comprising:

• a vehicle tilt angle sensor configured to sense a vehicle tilt angle;
• at least one condensation sensor configured to sense conditions associated with a condensation risk;
• and
• a voltage controller that controls a voltage supplied to the rear blower of the vehicle HVAC system if the sensed vehicle tilt angle and the sensed conditions associated with the condensation risk each exceed respective threshold values.
