sorry for the delay.............Greetings...... “Hi, I’m Don (akaCustomer and I look forward to helping you!”.Technically you should have GM Dealer use Scan Tool to isolate the problem.Typically it is the Amplifier that causes No Sound, but can be an issue with the BCM (body control module) Radio, Fuse or Speakers.The AMP is located in the trunk, behind the upper Back Seat.You need to remove the lower & upper back seat to accessTest the TAN / DARK BLUE wire at the AMP for Voltage + with Key ONThe BCM & Radio turns the AMP ON via DATA, so use of Dealer Scan Tool is needed to testapprx 1 hour labor.IF you need more information, please ask "prior" to Rating..
