I have not had a single major problem with my 95 deville for over a year. About 2 weeks ago the dash flashed and reset itself when i was driving home from work, and the tirn signals stopped working. Today i drove home froms school and the dash flashed off again. The mileage reset itslef again and the trip odometer. Now the turn signals work fine and the whole dash is reset, even the temp gauge was set back to 75 from 70. I don't know whats going on. Any help?
