REAR SEAT AUDIO

Chevrolet Avalanche

I have a 2003 Chevy Avalanche Z66 with 47,000, V8. It has rear seat controls for the radio and CD player that have just quit working. There is no power to those controls right now, nothing lights up. The power outlet below the controls still works, but nothing on the audio controls. I tried looking for a burnt fuse, but found none that looked bad. Any ideas on what else I can check for?

Do you have the original stereo or an aftermarket?

Yes, everything is factory.

Here is a schematic. You need to verify power and ground to the rear seat audio module.If the module has 12 volts and good ground,then replace the module.

Thank you for the schematic. It is a little small to read, is there someplace on line I can get a larger image of that schematic? I really appreciate your help.
