A control system for controlling the climate of a vehicle includes a control element, a temperature sensor, a motor and a microprocessor. The microprocessor may receive a temperature signal indicative of the temperature at the control element and may receive at least one further input. The at least one further input may comprise an input signal indicative of a high side voltage of the motor, a low side voltage of the motor, and/or an electrical current applied to the motor. The control system controls the motor via an output of the microprocessor. The control system may control the motor in response to the temperature signal and the at least one further input. The control system may reduce occurrence of high-power dissipative modes in response to a detection of a temperature above a threshold level via intelligent power management.
