Today my vette went crazy on me. All the gage lights came on and the DIC flashed reduce engine power, check gages, and tire pressure low. Along with that the power windows, locks, hatch and gas buttons don’t work. I checked the DIC for codes and only found this one that didn’t have a just a H behind it U1160HC. On top of everything my windows are stuck down is there a way to manually put them up?
