Hi,
If the radio is turning on, it isn't a fuse. As far as the chimes and blinker indicator, they come through the speakers as well, so that is why you are not hearing them.
Because of the model year, here is what I need you to do. The computer (audio system) needs to be scanned for diagnostic trouble codes. What needs to be done is a can-scan. Can stands for controller area network. Basically, all modules/computers are tied together via a few wires. By scanning the can-bus, it will identify any issues within any of the modules.
If you look at the first pic below, I highlighted codes related to the radio just so you can see I'm not crazy. LOL
Now, I don't know which system you have, If you look at pic 2, it shows the options. Let me know which one you have and that way I can provide you with relevant wiring schematics. Then we can try checking for possible issues. However, the can scan would be your best bet at this point.
Here is a video showing how it is done:

Let me know if you have the scan done. Also, let me know which system you have.
Take care,
Joe
