Hi I have a slight problem with my 95 blazer, I bought it with an aftermarket flame face gauge cluster and when I throw on my headlights everything comes to life except the lights for the numbers the needles light up with there bulbs but the blue numbers do not all my hvac cd player 4wd and exterior lights work just not my numbers in the cluster. I know they arent burnt out because they came to life once flickering then went out. Did I mention I also replaced my headlight switch and dimmer. What is causing this please help??
