2003 Yukon XL - My Service Brake System lights has been occasionally coming on. Took it to a shop and was told the Brake Control Module needs to be replaced. Since the light only comes on in hot weather, how is this module affected and is it either good or bad? It is cool in Fla now and the light rarely comes on. The job is estimated at over $1200 to replace and I don't want to waster money if it is a sensor.
