Nothing showed up in a search, so maybe no one has had this happen before. Every since the stealership replaced my heater core the radio makes a kind of chime sound every time I turn in on. I pulled out the radio, checked the wiring, etc and all seems fine. Other than the chime, it works fine. I really don't want to go back to the dealer since they are a fair distance away and screwed up a couple other things while doing the heater core.

1995 Disco, factory AM/FM Cassette.
