My audio in my 2011 PTT stopped working a few weeks ago. No sound from radio, phone or NAV. Checked PCM fuses, reset PCM, cleared codes and pulled and reseated the AMP in the floor board. Before I go and buy a replacement AMP, anyone have a wiring diagram or know how to test to confirm the issue? Is the A3 fuse in the trunk the fuse for the AMP?

I did confirm the optical cable appears to be on but the amp FAN is not spinning. The PCM system works fine otherwise, just no audio. Seems like the AMP but wanted to be sure. Also, for anyone who swapped it out did it require coding?

 

Check to make sure your audio source is not set to Aux
