My 2004 Deville has the standard sound system in it. Now the sound only come out of a small single speaker on top of the dashboard. what do I have to do to check if the amp. is blown or is their another problem.
I own a 2004 Deville and I have lost all power to my windows and locks from my drivers door. The interior lights also will not go off when the door is closed also. In a related issue my radio has stopped working, there is power going to it because I have the time etc. but no sound, the radio part doesn't turn on at all.
