The audio stopped working in my tahoe

The wires could be shorting or have a bad connection any where in the length from the radio to the sub woofer. I lost all sound in my Tahoe and thought that the connection was at the radio but never found a problem. One day on a hard left turn a loose chair in the back area of the Tahoe struck the right side panel which has the speaker and everything starter working.

First step is to check ALL fuses,with the key on.Use a 12v test light and check then in place.Each fuse will have a small area on the top of each fuse at each end that can be probed with the test light.If both ends show power then the fuse is good.

it sounds like a broken wire in the passenger door.

Here you go. Be careful this can disable the truck in some models due to the radio system be tied into the factory anti theft system..

Yes, quite a few like in the radio itself. If the fuses are all intact it looks like a job for a repairman.

if you dont get even a pop or crack when turned on at first, check the radios memory on the read-out on the radio face and see if its on mute setting, and if this is not the case, there are 2 fuses,one controls memory power and the other controls audio output power, check both as if one fuse is out the other cant make the radio operate properly

try a couple of things before tracing wires,first check the switch at the pedal,then the ground wires at each tail light
