2016 Tacoma access cab speaker problem

i have a 2016 tacoma access cab, the front passenger speaker is not working. I automatically assumed the speaker was the problem, so i changed both front speakers. It didnt fix the problem. I removed the stereo hoping for find a burnt terminal or loose wire. No luck with that either. The truck is no longer under warranty.

Any suggestions??

 

Check that you have output from the head unit/amp and that you have continuity in the harness on that speaker. It's gonna be one of those two things since you know it's not the speakers.

Of course this is assuming you've checked the settings on the head unit. You've probably done this, but I went out on a service call today only to discover that the customer's amp was switched off. People overlook the simplest things sometimes.

 

Thank you I have tried everything my abilities allow. It is under warranty. I have an appt. with Toyota
