In the last two years of driving my 1984 Cutlass Calais, I have observed my radio going in and out of Stereo illuminated display as well as the sound on my radio. Has anyone experienced this issue? If it happens to be a radio problem is there anyone that services the radio. The 1984 Cutlass Radio has cassette and equalizer components. I am in the Chicagoland Area, I did not know if FM Stereo Broadcasting has changed where the radio old radios could intermittently receive??
