Place multifunction switch in appropriate position. Measure voltage at terminal No. 3 (White/Light Blue wire for left turn signal; Light Green/White for right turn signal) at appropriate instrument cluster harness connector. See Figure or Figure . Voltage should pulse between zero and battery voltage. If voltage is as specified, replace bulb or instrument cluster as necessary. If voltage is not as specified, repair open or short in appropriate wire.
