1992 Sierra CDM/radio receiver

they do sell a aftermarket set up where you can put a smaller radio where your EQ is, thats what i ended up doing in my 1990.

one thing you can try but not going to promise it works is try unplugging your EQ and see if that fixes it. i had the same issue where my radio turned on but didnt do anything so i went and bought the insert for the center of the dash to put in a aftermarket radio, when i removed the EQ the radio started working the second i unplugged it. i installed the aftermarket radio anyways as i wanted to use my ipod with it.

its worth a shot i guess
