Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.
Voltage is applied at all times through I/P Fuse Block CTSY/PWR MIR Fuse to the Body Control Module (MALL). When a door is opened or the Interior Lamp Control is operated, the MALL Module provides a ground path to the Courtesy Lamps. The Courtesy Lamps, which includes the Rail and Warning Lamps (if equipped), then light. After the closing of all doors, the MALL Module will provide the Interior with a ground for about 25 seconds, provided no other inputs are received.
The data base doesn't show the part number for it. You will normally have to go by the numbers on it and you will need to get it from GM.
