I changed the stereo to an after market stereo. Since I changed it the lights in the Water Temp, Oil Pressure cluster do not work. You can see the numbers like fuel mileage changing so it is working but they are not aluminated. The Tach and Speedo work fine. I put the original radio back in with the same results. My question is how do these panels aluminate? Is it one bulb? I checked fuses all are good.
