Ford Crown Victoria Forum : “clock and radio”

It is possible the radio unit itself is dead, try replacing it with a known good unit or one from a junkyard that has been tested and works.  If this does not correct it you have a wiring issue and will need to see a mechanic.

If the light for the clock and radio went out , but , the radio still works , it might be that a bulb burned out. If both stopped working  at the same time, and they are both located inside the radio , and the fuses are all ok , you will need to have the radio removed and repaired/replaced.
