My Cadillac DeVille 1995 dashboard light won't go off after ignition is turned off.

Were you able to find and fix the issue? Mine is doing the same now. Had a new alternator and battery put in, but disconnected the battery again, since the dashboard lights stay on. Any advice is appreciated

I have a 1979 Cadi, Deville and my interior lights would not go off.I disconnected the battery and I found out that that will reset the brain but every time I have my car worked on and even a tire changed it does the same thing
