My dash board lights blink on and off from time to time
My dash board light goes on and off from time to time. The lights that shows the mileage and also my trip mileage only light up half way or in other words only the top part of the lights work. if I hit the top of the dash board sometime they will come back on but will go back out after a while. does anyone know what causes this problems. could it be the speedo cluster needs replaced? Are there blubs that need to be changed?
