Which radio model do you have?

factory the one that came in the car 1995 Lincoln Continental

That doesn't help. There were a half dozen different models available. Some had the cassette player built in. Some had CD. Some had remote CD players.

If you have just the AM / FM radio or the base model with cassette, those are not repairable. Those are one of only two factory radios it doesn't pay to try to fix because things will just get worse. Some of the small capacitors leak out their oil which is corrosive to the copper circuits on the circuit boards. Any attempt to disassemble the radio results in more of that copper crumbling. That causes more new problems such as no FM, dead left-side speakers, etc.

This is one of the few instances where an aftermarket radio is the best remedy.
