My wife's 2001 Tarusus has no dash lights except when the temp inside the car has been over 100. The problem started several years ago, she would start up the car and there would be no dash lights, only the turn indicators on constantly. After driving down the b;ock the lights would come on. Over the next year it took longer and longer for the lights to come on. Now as I've said the lights only come on when the temp had been over 100 inside the car. The lights on the stereo consoul work, but sometimes they blink with the turn signal. any ideas??
