Abstract
The present invention provides a vehicle air conditioning system including a condenser, condenser fan, a variable expansion device, an evaporator, evaporator fan, and a compressor. A processor is provided in cooperation with the compressor for temporarily interrupting compressor operation under certain predetermined operating conditions in order to prevent sticking of the variable expansion device. Various algorithms and initial algorithm engagement parameters are provided for temporarily interrupting compressor operation under certain predetermined operating conditions.
