Started our 99 Pontiac Montana the other morning, and the ABS, Traction Control, and Brake lights stayed on. The TCS switch in the console had no effect. After driving for 20 minutes, they were still on. today, 3 days later, the lights were on for about 10 minutes till I stopped at Starbucks and when I restarted the car, they stayed off. The car has 140K miles, with the transmission having about 3100 miles. It is the extended length. The weather has been cold and icey here in the midwest. Please help!

Sounds like a wheel speed sensor problem. I would think that you would be seeing a 'check engine lamp' illuminated, as well. Scanning the PCM should solve the mystery.
