i have a 97 k1500. i went to turn on the lights one night and i don't have and back lighting on the dash. all the gauge lights, the heater control lights don't work. the blinkers, blue brights light, green lights light, and all of the other service lights work both when the lights are on and off. somebody told me that it could possibly be a bad resistor in the dash lights dimmer switch and that the switch supplies power to those lights. i've checked all the fuses obviously but i don't understand why the dash lights won't work but the service lights would. any help would be great, thanks.
