Im selling my 1996 impala ss and the deal breaker is the digital odometer, wont light up to show the miles. I have replaced the two small ''resistors'' on the circuit board, in the back of the cluster several times. It still goes back out in a few days, I think I have the wrong size resistors. What is the correct size and should I look over the rest of the circuit board for a short that may be causing it? Help !!!
