Radio have power but no sound to car stero speaker what maybe the problem

cobolt known for speaker[s] [drivers side] blowing when speakers go so does the chimes

You can't disable it , sound comes from the radio out of driver door speaker . The BCM - body control module sends this signal to the radio on serial data bus . A faulty input signal to BCM - door ajar switch probably . You need to take it to a qualified repair shop .

It comes through the radio an left front speaker .
The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings through the left front speaker. The radio receives audible warning requests via the class 2 serial data line. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. The Multifunction Alarm generates the audible warnings on vehicles with RPO UL5 -- Radio Delete Option. The following lists the audible warning priority and the pulse rate:
The radio activates the door ajar audible warning as requested by the body control module (BCM). The BCM sends a class 2 message to the radio indicating the chime frequency of a medium rate and at a continuous duration. The door ajar warning sounds and the door ajar indicator illuminates when the following occurs:

1. The body control module (BCM) determines that the driver's door is open and the signal circuit low. The IPC receives a message via class 2 from the BCM requesting illumination of the door ajar indicator.
2. The vehicle is not in park. The BCM receives a class 2 message from the PCM indicating the gear position.

Class 2 Serial Data Link
The class 2 serial data link allows the following modules to communicate and share data with each other:
?€¢
Auxiliary Power Drop Connector

?€¢
Body Control Module (BCM)

?€¢
Driver Information Center (DIC)

?€¢
Electronic Brake Control Module (EBCM)

?€¢
Instrument Panel Cluster (IPC)

?€¢
Powertrain Control Module (PCM)

?€¢
Radio

?€¢
Remote Playback Device-CD Player (if equipped with UQ3)

?€¢
Inflatable Restraint Sensing and Diagnostic Module (SDM)

?€¢
Vehicle Interface Unit (VIU) (if equipped)

The class 2 serial data link allows a scan tool to communicate with the above modules for diagnostic and testing purposes.

the chime actually is done with the radio. the front drivers door speaker. so if the radio works and the front left speaker works. then more then likely you have a defective door switch. located in the door jam that controls the dome light

somehow I was the annoynmess person with the question about the door ajar and a seatbelt alarm that we disabled, and odometer quitting the radio stayed on well it was just a plug and the odometer speedometer all that works now, but the radio still stay on with a key out of ignition, and now the AC don't cool

There is another legitimate and easy way to disable seat belt chime. Radio is supposed to stay on til door opens. That is correct

try this
disconnect battery
undo the fuse box and look at the wires behind that fuse you pulled

check that only radio and clock wiring are fitted there

the chime may its own power source

i could be wrong
i thought chime was separate to sound system speakers
and comes from a small but loud sound device on the instrument panel circuit board ..much like a computer

Chimes are generated by the radio. Unplugging the radio and then plugging it in can activate the security feature in the radio and is very unwise. You can try resetting it by disconnecting the negative battery wire, then plugging the radio in and reconnecting the battery wire. If that doesn't work, check with a dealer to see if they can reset it, but if the radio has been damaged by what you are doing, you may have to replace it.

Some are on a button or lever in the door jamb and ford likes to attach them to the door latck in the door. A good blast of penetrating oil into the latch in the door will loosen it up.

one of the positive power wires to the speakers is shorting out.alot of times it's the door speaker wires.
