Hey everyone, this is my first post on this site. I have an 03 Deville and the door panel controls do not work. I cannot lock/unlock the doors, I cannot roll the windows down or up. Also, when I turn the car ignition off and open the driver door, the radio stays on instead of turning off like they are supposed to. The radio stays on until i open any other door, I usually open the rear driver side door to lock the doors and make sure the radio shuts off as to not kill the battery. I am not sure if it is a fuse problem or not. Thank you in advance for the replies
