No Illumination In One Panel Component Test
- Check for blown fuses and bulbs first. If fuses and bulbs are good, turn headlight switch to ON position and set panel dimmer switch to BRIGHT position. Check for battery voltage to instrument panel component or to illumination bulb being tested. Refer to the WIRING DIAGRAMS .
- If battery voltage is not present, repair open in circuit. If voltage is present, circuit is okay. Check continuity of ground wire for instrument panel component or ground for illumination bulb socket. If continuity is present, circuit is okay. If continuity is not present, repair open in ground.
