Turn Signal Indicator: Testing and Inspection
The diagnosis found here addresses an inoperative turn signal indicator lamp condition. If the problem being diagnosed is related to inoperative turn
signals or hazard warning lamps, be certain to repair the turn signal and hazard warning system before attempting to diagnose or repair the turn signal
indicators. If no turn signal or hazard warning system problems are found, the following procedure will help locate a short or open in the left or right turn
signal indicator circuit.
1. Disconnect and isolate the battery negative cable. Remove the instrument cluster.
2. Connect the battery negative cable. Activate the hazard warning system by moving the hazard warning switch button to the ON position. Check for
battery voltage at the inoperative (right or left) turn signal circuit cavity of the instrument panel wire harness connector (Connector C2) for the
instrument cluster. There should be a switching (ON and OFF) battery voltage signal. If OK, replace the faulty turn signal indicator bulb. If not
OK, repair the open (right or left) turn signal circuit to the left multi-function switch as required.
