99' Cadillac DeVille car starts up but no power to radio or Windows.. checked all the fuses and new battery
Car starts but no power to Windows or radio.. new
battery and checked all the fuses... after starting
the dash lights come on, but no information
displayed( gas mileage, etc.)
Sounds like you have lost the power supply to the BCM, check for blown fuses, if none are found then the system needs to be checked and hopefully just reflashed.
