I have an 03 tahoe the the steering wheel controls. The radio controls work normal but the DIC buttons don’t do anything.there are also some settings that need to be changed such as driver 1 setting is in French and some others. I suspect the instrument cluster has been changed because it shows 235000 miles and the truck seems to be in too good of shape to have that many miles (ie. no brake light or abs light on dash or check engine light no oil leaks) The instrument cluster that is in it is part number is 15114649. Is that the correct cluster for this truck.
