2002 Pontiac Montana, 165,000 miles. I am the only owner. Very reliable service. Front wheel bearings have been replaced twice. Traction System OFF light came on at 155,000 miles, and cruise control broke at same time. Lived with that, but then rear brake lights went out and mechanic cleaned out the rusted rear light circuit boards, which made everything work again. Mechanic told me that rusty circuit boards are common for Montana. Mechanic suggests replacing 2 circuit boards next time for $250.
Have you tried looking behind the center vents above the stereo?
This code stands forCruise Control Command Switch Assembly Circuit Failure
