1	Did you perform the retained accessory power (RAP) diagnostic system check?	Go to Step 2	Go to Diagnostic System Check - Retained Accessory Power
2	Install a scan tool. With the scan tool, observe all door jamb/liftgate switches. Open and close each door. Does the scan tool display change from active to inactive?	Go to Step 3	Go to DIAGNOSTIC SYSTEM CHECK - LIGHTING SYSTEMS in Lighting Systems
3	Close all of the doors. Turn the ignition switch to the ON position, then to the OFF position. Wait 10 minutes. Attempt to operate the sunroof and/or the rear quarter power vent windows after 10 minutes has elapsed. Do any of the items operate after 10 minutes has elapsed?	Go to Step 4	Go to Step 12
4	Remove the RAP relay. Attempt to operate the sunroof and/or the rearquarter power vent windows. Do any of the above items operate?	Go to Step 7	Go to Step 5
5	Test the RAP relay control circuit for battery voltage, after the 10 minute timer has elapsed, at the RAP relay socket. Refer to CIRCUIT TESTING and WIRING REPAIRS in Wiring Systems. Does battery voltage exist after 10 minutes has expired?	Go to Step 6	Go to Step 11
6	Remove the harness connector from the BCM that contains the RAP relay control circuit. Test the RAP relay control circuit for battery voltage, after the 10 minute timer has elapsed at the RAP relay socket. Does battery voltage exist after 10 minutes has expired?	Go to Step 8	Go to Step 9
7	Repair the short to voltage in the RAP relay output, which feeds the Sunroof/and/or the rear vent windows. Refer to CIRCUIT TESTING and WIRING REPAIRS in Wiring Systems. Is the repair complete?	Go to Step 12	-
8	Repair the short to voltage in the RAP relay control circuit. Refer to CIRCUIT TESTING and WIRING REPAIRS in Wiring Systems. Is the repair complete?	Go to Step 12	-
9	Inspect the BCM for poor connections and intermittent faults. Refer to the following in Wiring Systems: TESTING FOR INTERMITTENT CONDITIONS AND POOR CONNECTIONS CONNECTOR REPAIRS INDUCING INTERMITTENT FAULT CONDITIONS TESTING FOR ELECTRICAL INTERMITTENTS Did you find and correct the condition?	Go to Step 12	Go to Step 10
10	IMPORTANT: Setup and reprogram the module. Replace the BCM. Refer to BODY CONTROL MODULE REPLACEMENT in Body Control System.Did you complete the replacement?	Go to Step 12	-
11	Replace the RAP relay. Did you complete the repair?	Go to Step 12	-
12	Operate the system in order to verify the repair. Does RAP power mode function normally?	System OK	Go to Step 1
