Repair radio 2008 cobolt spekers front spekers don't work

Did a qualified repair shop replace it ? If not , maybe you should take it to one .

If you have no radio repair places in your geographic area, I would type radio repair into the search engine of your computer, and you should find palaces that advertise that service for you.
I have used them, it works.
You have to take the radio out yourself and send it in.
God bless your efforts.

If you are going to work on your car.. Purchase the Chilton manual for your car..Makes it a whole lot eaiser..

Hi,
How did they break in? Does the ignition lock work normally when the key is inserted?

Td

Possible broken wire between door and body. May be dirty knob in radio. You can spray with crc electronic cleaner and rotate back and forth. Spray the rod not the button. Check for broken wires. Connector may be bad inside door also.

Well it is obvious that the radio has a failed circuit board and the noise (electrical) that it creates is triggering mute. You will need to remove the radio and send it in for repair to an authorized GM electronics repair center, If you click this LINK it will take you to a on line GM radio repair business, call them.

The other speakers could be blown or radio/cd/tape may be going out

It should be under the hood in that fuse panel labeled pwr outlet
