FIGURE 3
Disassemble the cluster and remove the small odometer connectors from the speedometer circuit board. Connect I/P Tester J-33431-3. See Figure 3.
Plug in the I/P Tester and set it to "On", "54 mph", and "60 Hz". With the odometer test switch held down, the Odometer should turn and change
the mileage shown about one mile per minute.
^
If the Odometer does not turn, replace the stepper motor.
^
If the Odometer does turn, check the connector that joins the Odometer to the speedometer circuit board. If the connections are good, the
condition is in the speedometer circuit board. The Speedometer is to be sent to an authorized AC-Delco Service Center for repair.
