I can't say for sure on a 2005 but on a 2010 the code is C66.If it has the option the car would have the condenser,the evaporator and the expansion valve already installed,the less obvious would be the wiring for the compressor and pressure sensor.If you read my posts you will see what you are in for.Don't expect any help from GM.
