MERCURY MARQUIS RADIO PROBLEM

1999 Mercury Marquis • V8 2WD Automatic • 175,000 miles

The sound from my radio keeps cutting in and out. The radio turns on and the led light come on and the channels change. Sometimes I have sound and sometimes not.

It sounds like there is a circuit board level failure. There is not way to test for this as only manufacturers would have test fixtures fo circuit boards. You will have to replace the stereo as a unit.
