Check the following Oldsmobile Service Bulletin, this maybe? your problem.If not I suggest you get the car to a good experienced electrical tech. Let us know what you find out.
FYI. The BCM controls body related outputs based on inputs from various other modules and sensors and stores trouble/fault codes (DTC's)
Good Luck,

Subject: Cruise Control, Entertainment System, Interior Lights, Power Windows, Power Sunroof Inoperative, DTCs B1477, B1482, B2617 Set (Inspect Wiring Above Headliner)
Models: 2000-2002 Oldsmobile Intrigue
--------------------------------------------------------------------------------
Condition
Some customers may comment that the following features are inoperative:
• Cruise control
• Entertainment system
• Garage door opener
• Interior lights
• OnStar® system
• Power sunroof
• Power windows
• Retained Accessory Power (RAP)
• Redundant steering wheel controls
Some may comment that these conditions occur intermittently. Diagnosis of these conditions may also find that Diagnostic Trouble Codes (DTCs) B1477 (RAP relay short to ground/open), B1482 (Inadvertent power bus short to ground), and B2617 (Theater dim short to ground/open) may be set and the Inadvertent Power Bus/Rap fuse may be open (blown).
Cause
The condition may be caused as a result of the wiring harness, which is located above the headliner, being chafed or pinched where the sunshade pivot arm goes through the headliner material and into the roof sheet metal or at the roof side rail lamp.
Correction
Notice: When removing the sunshades, be careful not to damage the bezel on the shaft, as it is not serviced separately.
Important: When diagnosing any of the above conditions, do NOT replace the Body Control Module (BCM) until after thoroughly inspecting for a chafed or pinched wiring harness at the locations described. If there are no indications of any chafed or pinched wires, then proceed to the appropriate Service Manual diagnostics and only replace the BCM if instructed.
Remove the sunshades and roof side rail lamps, one at a time, and inspect the headliner wiring harness for a short to ground or an open. Repair the wiring as required. When reinstalling the sunshades, route the sunshade vanity mirror wiring harness back into the notch (cutout) in the roof sheet metal to prevent the harness from being pinched during reinstallation. Replace the 15 amp Inadvertent Power Bus/Rap Fuse, located in the fuse block on the right side of the instrument panel, if necessary. Clear all diagnostic trouble codes that may have been set.
