need to find good or excellent repair for radio that is in an excellently kept 1989 chevy.celebrity.
You’ll improve your chances if people know where you are. Even then it’s a long shot. My advice is to try a web search. Failing that a car audio shop might be able to replace the unit.
just do a search for automotive radio repair shops. there is a lot out there.
A bunch of them here
Most likely a replace rather than repair situation.
Check you YouTube videos, you may decide to do it yourself.
I had the radio/CD player fail on a 98 Explorer. I first went to a big box store that offered “free” installation on any unit >$100. Fine, then I saw they were charging $50 for the three $10 adapters required. I went elsewhere, bought a better unit and the adapters. Took about an hour to switch out less than $200.
Can Chevrolet Celebrity and Classic be in the same sentence ?
Perhaps “Classic” is the trim level?
