  1. Operate turn signals. If turn signal indicator lights illuminate properly, go to next step. If turn signal indicator lights do not illuminate properly, go to step  6 .
  2. Set headlight switch in park position. Set instrument panel dimmer switch to maximum brightness. If A/C-heater control illumination lights illuminate, go to next step. If A/C-heater control illumination lights do not illuminate, locate and repair problem in interior light dimming system. See appropriate wiring diagram in ILLUMINATION/INTERIOR LIGHTS article.

If reading is not 9-14 volts, go to step  5 .
  4. Check illumination bulb(s) and bulb connection. Repair as necessary and recheck system operation. If bulbs and bulb connection are okay, replace instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Recheck system operation.
  5. Repair poor connection or open in circuit No. 8 (Gray wire) between instrument cluster connector C2 and splice S203 (located in instrument panel harness under right side of instrument panel, about 4" from radio breakout). Recheck system operation.
