A method and system for controlling a cooling fan that cooperates with an air conditioning condenser in a vehicle. The present embodiments include steps and corresponding implementations for determining a speed of the vehicle, determining a discharge pressure of the air conditioning condenser, determining an ambient temperature of air surrounding the vehicle and determining an outlet temperature of a vehicle air conditioning system. The cooling fan is operated in one or more desired fan speed modes corresponding to one or more respective discharge pressure ranges. The fan speed modes are a function of vehicle speed and one or more of ambient temperature, outlet temperature, and discharge pressure.
