I have and all factory system in my 03. The single CD changer/radio/casset. Last night I get in my truck and no music is coming out the speakers, not static but just no sound to any of my speakers. It worked 2 hours before fine. I could change the station, change CD’s, volume, turned it off and on a couple times, everything looked like it was normal, just no sound. I turned off the truck and restarted and still nothing. On my drive home part of the way I let it on and no sound, then just turned it off. Today I get in the truck and turn it on just for grins and it worked fine? So now it works and that’s all I care about but I’m just wondering if it is some kinda sign. Anyone hear of this? Oh…..it wasn’t overly hot that day and I wasn’t blasting the music before it decided to die on me.
