The Car: 1992 Seville, 4.9L PFI
Below I have pasted a copy of a TSB issued for my Seville. It was experiencing this problem and so I replaced the RAPIE module with the one listed. This has fixed the flashing interior light/battery drain problem but now I have absolutely no RAP function. When turning the key to off, all systems shut down like an old non-RAP car would. All items function normally when the car is running. Placing the ignition switch into ACC also powers everything normally. All I did for this fix was unplug the old module and plug in the "new" one I got from a junkyard. I can't rule out a bad RAPIE module, it was used afterall, but I don't have another to test with. Or is part of the "fix" the new module incorporates is to just disable RAP function? I'd like RAP to be functional.

Parts are currently available from GMSPO.
To diagnose these conditions check for a short to ground at the RAPIE module terminal A7. Refer to Service Information Manual Section 8A-114 for circuit diagram, and Section 8A-201-32, Figure A for component location. The short to ground may be caused by a shorted door handle switch (P/N 16626131), malfunctioning RKE module, or circuit 157.
