Passenger side door speakers not working

I have a 2012 tacoma 4cyl access cab base model and after putting about 40 miles on it my speakers stopped working. I took it to the dealer 2 times, once to put the new speakers in and that did not work so the second time was for a new radio, that did not work either. Now I'm waiting to see what Toyota in California says? Anynbody else have an issue with no sound in the passenger side door speakers?

 

Two items changed... looks like some type of wiring issue?? Or the harness its self.

 

That's what I'm afraid of.

 

If it is Toyota will take care of it. Shes still new.... Unlike mine everything is out of warranty... LOL.

 

It's gotta be wiring. Try to get something for your time, that should not happen on a new vehicle!

 

I know, I feel I should get something but I'm bringing it to a local dealer not the dealer I bought it from, I wouldn't blame the dealer anyway, I know it's not their fault. How do you recomend getting something? Writing to Toyota?
