MODELS/YEARS:
1991-92 NINETY EIGHT
1992 EIGHTY EIGHT WITH ILLUMINATED ENTRY (C97)/RETAINED ACCESSORY POWER (KP2)


CONDITION:
Some vehicles may exhibit an intermittent dead battery or the power windows may operate after the door has been opened with the ignition key removed from the vehicle.

CAUSE:
A voltage spike from the Brake Transmission Shift Interlock (BTSI) Solenoid may cause the contacts of the number two Retained Accessory Power (RAP) relay to stick closed.

CORRECTION:
Install a new BTSI solenoid, Part Number 26036913, which is currently available from GMSPO. The new solenoid can be identified by the gold color. Refer to the service manual for the correct installation and adjustment procedure. The RAP 2 relay located in Position "J" of the [1][2]relay center should also be replaced since the contacts may be pitted. Use the relay that is listed in the current parts catalog.
