The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
There is no sound from the radio, but the display works fine. The radio stations can be changed and the volume on the display will also change.
Recommendation/Instructions:
- Pull the following fuse that powers the amplifier. On a Monte Carlo, this is the fuse labeled (AMP), On an ION this is fuse 21 labeled (RADIO), On a VUE this is the fuse labeled (PREM AUDIO) and on the Saturn Aura this fuse is listed as Audio AMP
(Fuse 13) in the RBEC.
- Reinstall the fuse, then recheck the radio for sound.
| • | If the sound returned after cycling the fuse, replace the Amplifier/Booster. On the Monte Carlo, this is called the Audio Power Booster and can be found in the parts catalog in group 9651. |
| • | If the sound did not return, follow the eSI Document for (Speakers Inoperative - All) |
| - | Document ID# 1686457 for the Monte Carlo, or Document ID# 1448888 for the ION/VUE |
| - | Document ID# 1843082 for the Saturn Aura. |
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
