Hello, I have a 2000 blazer. All the lights on the gauges have gone out besides my millage, PD321, and warning lights. As for the lights behind that speedometer, fuel, and so forth do not work at all. I have taken out the cluster to check the bulbs but they are not blown, and my fuses are fine. any ideas on whats going on??? need help b/c idk how fast im going when its night time unless i use my phone to shine on it.
