When using the schematics for the Moveable Windows or the Door Lock/Indicators, it is necessary to identify what power window option the vehicle has. The RPO code for the power windows may not be listed in the GM Vehicle Inquiry System or on the Service Parts Identification Label. Also when using a scan tool it may be found there is no communications with the drivers or passenger's door modules. Some of the vehicles use a Driver and passenger door module, and some do not.
