pulled the instrument cluster to fix a few things. reinstalled and the IC night lights don't work. on the bench, all the lights work. have 12 volts from the light switch to the plug but somehow, the power is lost soon as I plug in the IC. where did the power go ? blinker work, wipers work, brake work, high beam lights work, courtesy lights work, but not the ic night lights. I can get the IVR to pulse on an analog meter. I can read 12 volts off the light switch but cannot get the volts to decrease as i rotate the light switch rheostat. any suggestions?
