Circuit/System Verification

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Radio ON, verify clear audio is heard from each audio speaker.

If audio is inoperative from all speakers, replace the radio.
If audio is inoperative from one or more, but not all, speakers or the audio emitted from the speakers is not clear, test individual speaker circuits.
