2002 Cadillac Deville

Help! My 2002 Cadillac Deville’s Service Electrical System light recently came on and since then the Traction
Control Warning light comes on periodically, the brakes lights are staying on all the time when the car is running and when I turn the car off I have to press the brake pedal for them to go off, the cruise control no longer works, the back windows wont roll down, and the check engine light is on. Any suggestions or similiar cases???

Just take it to a good local mechanic and have them look at it. Don’t drive around this way - driving w/ your brake lights on is dangerous.
