2001 Silhouette rear audio not working?
I have a 2001 Silhouette, with the separate rear audio controls for the passengers. Currently there is no sound coming from the lift gate speakers, or the overhead speakers beside the video screen, and when you press the PWR button on the rear audio control nothing happens (no red light). I've tested the speakers and they are all good.
I'm assuming the rear speakers are routed through the rear audio control, so I removed the rear audio control, unplugged the harness at the back and tested the harness wiring for any voltage coming through when playing the radio from the front dash... nothing coming through.
Is there an in-line fuse or something that I can check for the rear audio control? Or what would be the next thing to check...
(BTW: The front speakers work great, VCR works, video screen plays fine and VCR audio comes through the front speakers.)
Thanks a lot for any suggestions
