FYI - Almost the same issue with 1999 Malibu...
Cruise control works during the day but not at night. Appears to be related to the bulb monitoring system, the BCM thinks the taillights aren't working because of the resistance being too low and has been programmed to make this an 'issue'. Verified by putting regular bulbs back in place and all works fine. Will have to add resistors to the car someday soon which I had been planning to do anyhow as the 'hyper blink' is somewhat annoying to me.
