Cadillac water and no sound issues.

Hi,

Did the amp in the trunk or the fuse box under the rear seat get wet? Also, I need you to check the fuse again for both the radio and the amp. The fuse could be good but not have power. So, in addition to checking the fuse, I need you to confirm there is power available.

As far as the sound for the signals, it is supplied by the audio system. Since it isn't working, you have no signal audio indicator.

Let me know about the fuse. Also, let me know if the fuse box or amp got wet.

Take care,

Joe

See pics below. The radio is on the left. Also, the fuse box is under the left rear seat. Pic 2 shows the fuses to check.
