My 2008 chevy pickup is having issues with the radio not putting out sound to all the speakers and then it works once in a while.

It seems like a harness issue, but I was wondering if its an electronic issue before I tear everything apart.

Any one have similar experience?

I have had shorts in speakers do the same thing.

This might help you out, especially considering all the rain we've had lately. Take off a door panel with a dead speaker and see if it's wet. If so, there's your problem.
