RADIO HAS NO SOUND

Can you be more specific? Is the sound coming from the steering wheel area? Sorta like arching or sparking sounds?

The bcm controls that device for the addition of features like blue tooth and hands free, on-star etc.

Either radio is bad, or you have a loose connection to speakers, or poor ground connection at the radio. If a poor ground connection, the radio will intermittently not work also. Since radio continues to work, but sound does not, it is probably a bad audio circuit in the radio itself.

Hi,
Unless you take it to a shop to diagnose it, I would guess that it is due time to replace lambda sond,
The lamda sond is normally located a little down the exhaust manifold, maybe covered by a shield.
Good luck.

the first thing i would do is to have the batttery checked, if the battery tests ok then iwould have the starter tested. this sound slike you may have abad starter.

sond like the torque converter came apart trans will need to come out highly suggest torque converter from tci

well you have to change it and your car is not very envirmently friendly with the lambda sensor you will use extra fuel, it will run shity........ get an mouth spaner and loosen it and unplug it and twist it out..

it sond like its an electric motor and maybe the motor isnt working i have a 99 firebird conv and if it is it shouldnt have any type of resovor

First disconnect the battery and the reset switch is located just beneath the dashboard just above the throttle pedal. un-clip the casing via screws and open it and press the switch. Re fasten case and replace back into position. Reconnect the battery and you're set

One easy way to know which ones are the speaker wires is by using a double AA battery and connec one wire on any side of the battery and just tap the other side of the battery with a nother wire and when you find the right one you will hear the speaker make a sond keep doing this until you find all the speakers well I hop this helps.
