No ignition feed to the cluster. 1. Remove the large 17 pin connector from the cluster. Using a digital volt- OHM meter, measure the voltage from pin A13 to ground with the ignition in run. The meter should read battery voltage. If the meter reads less than battery voltage, or zero, repair the pink/white wire from the ignition 2. No ground to the cluster. 2. Measure the resistance from pin A15 switch. and A16 to ground using a digital volt- OHM meter. If the meter reads any- thing but 0 - 0.5 OHMs, repair the 3. Inoperative cluster black wires at A15 and A16 to ground. 3. Replace the cluster. Cluster Display Does 1. Park lamp feed open or shorted. Not Dim With Lights 1. Measure between pin A8 of the large 17 pin connector, and ground using a On digital volt.OHM meter.

Measure between pin A8 of the large ed 17 pin connector, and ground using a digital volt-OHM meter. Ignition in run, parking lamps on.Adjust the panel lamp switch from high intensity to low intensity. The vollmeter should read between 0 to battery voltage. If this reading is not obtained, repair the gray 3. Cluster inoperative. wire and/or the park lamp switch. 3. If the previous 2 steps are OK, replace the instrument cluster.
