When we bought this vehicle a year ago was told the bcm was bad but just got it back from chevy and they said something about the data lines are down on the car so they couldn't program the new bcm but when you turn the key to on only light that comes on is the check engine light no radio lights dash lights etc. heater doesn't even turn on DIC has nothing on it either. Windows will roll down and up cigarette lighter works etc. any suggestions would be appreciated! Thanks in Advance!
