It sounds like the Body Control Module (BCM) took a dump. They're about $50.00 at a junk yard, $500.00 for a rebuilt one from a dealer. It's located behind the fuse panel under the dashboard.

If you get a used one, make certain that the part numbers match.

Good luck! The BCM provides the following features:
• Automatic door locks
• Battery protection
• Chimes
• Compass/mini-trip support
• Courtesy lamps
• BCM diagnostic support
• Door lock inhibit
• Headlamp time delay
• Ignition key lamp
• Illuminated entry
• Instrument panel dimming
• Mechanical instrument cluster support
• Power door locks (with/without remote keyless entry)
• Sliding door memory lock
• Vehicle Theft Security system (VTSS)
• Windshield wipers / washers (front and rear)
