2008 Chevy Cobalt: cd player and radio will not work. The dispay screen is black. There is no audio either. Also, when I hit my blinker, the clicking sound doesn't happen anymore but both of my blinkers work. No other problems noted other than the ones mentioned above. Did I blow a fuse?

The blinker sound is through you door speaker. Need the radio to work properly to hear the blinker.

check sensors for reverse will stop radio from working, try pulling fuses for all items at one time to reset. (backup cam , radio cd player, clock and memory)

What is your question ?

You can set the time by following these steps:

O
knob, located in the
center of the radio, to turn the radio on.
2. Press the

or let the screen time out

Replace the radio with either an aftermarket unit or get a factory replacement at a salvage yard.

Could be the BTSI solenoid in the shifter, have that checked . You may have to buy complete shifter if it proves bad. This would keep you from removing key. Call you local dealer with VIN number and mileage have them check for the recall pertaining to the key rotation, yours may or may not be involved.

You will need to have the radio reset or checked out at the dealer.Ther could be a cd stuck in it.Or the radio/CD player may have be on when the battery power got to low.

Hi i have a 2008 chevy aveo the dashes lights up but the radio stations wont whats wrong

I believe so, there are some audio jacks that are converters from a power source, such as, a lighter jack.
