Abstract: A method and apparatus for controlling blower speed of an air conditioning system in a vehicle having a start/stop engine. When an auto stop event of the start/stop engine is entered, an ambient temperature and a second temperature (e.g., evaporator) of the air conditioning system are measured by sensors. A first cutback limit is determined in response to the ambient temperature. The blower speed is ramped to the first cutback limit by a controller. The engine is restarted and the blower speed is restored in response to the second temperature reaching a restart threshold.
