I have a 2004 Buick Rainier and I sent it out to get detailed yesterday. Today it came back and when I turned it on there was no sound coming through the speakers. The radio has power and all controls work on the radio and steering wheel. Also, the door chime no longer works. I checked the fuse for the AMP and Radio and neither are blown. Everything was working fine until I had the car cleaned....any ideas?!?!?!?!?!?
