No absolutely not. The Ecm has nothing to do with these system. You may be referring to the bcm which does control lighting but not the radio. We need to diagnose your problem. Do you have a scanner one that would pull codes from the bcm? If not it will be hard for us to properly diagnose you have already checked all fuses. If you are interested in fixing this I can tell you a scanner that I recommend for people to buy it is cheap and will get the job done. If interested let me know.
Yes sir and thank you can I call u this mornig
Sir please allow me to apologize, i had something come up and could not help it.
Sir I apologize for the delay. A scanner I use and recommend is the Eady diag made by Launch Corp. It sells for less than 100 bucks comes with 2 free csr lines and will give you factory level access to codes. Please note that it requires a smartphone to operate. Your problem is associated with your radio and will most likely be a bad amo, speaker issue. You could pull the radio and remove speakers one at a time and see if your problem went away. But having thr scaner will give you access to thr trouble codes which will point you in thr rigjt area
