1991 240sx cluster lights
 

I have a 1991 240sx coupe se. The cluster lights were not working when I got the car. I did some research and found a guide saying to take the white box, next to the fusebox, open it and check for any burnt out resistors. I did that there was nothing wrong with the circuit board that I can see, so I put everything back together. After putting everything back together the cluster lights were working, but the next day when I turn the car on to check them they don't work. Can anyone help me , thanks.
