Could be a defective head unit, or the speakers are blown. You would have to remove the headunit to be able to test the speaker system.

its likely the speakers, it seems many trucks are heaving issues with the stock speakers. i would get aftermarket ones. you could take the one that plays and plug it in where the bad one is to be sure.

Justin, I was thinking of having him just pull the headunit, disconnect the connector and use a AA 1.5 battery with 2 wires. Find the pins to the correct speaker, quick connect, if you hear a thump, speaker is good. Then goto the next pair.

Much easier than pulling door panels IMO.

battery will sometimes still produce sound even on a blown speaker, the reason i said its likely the speaker is because i believe i saw a tsb or recall for the newer trucks for the speakers going out

just fyi this is the tsb i think i was thinking of however doesnt apply here because it would take out all your sound. i have read lots of posts about the oem speakers on this generation truck being junk and having to be replaced, thats why i said i would go with aftermarket ones, better cost and far greater quality.
