Q: How to remove the speedometer and gauge clusters on Oldsmobile Cutlass?
A: On models from 1974 to 1977, the Speedometer and gauge clusters can be removed separately for service. To do this, start by disconnecting the negative battery cable. If the vehicle has an automatic transmission, disconnect the shift indicator cable on the shift bowl. Then, remove the three attaching screws and pull the cluster out enough to disconnect the wiring connectors. Finally, remove the cluster.
Q: How do you replace the printed circuit on the instrument cluster?
A: To replace the printed circuit on the instrument cluster, start by disconnecting the negative battery cable. Then, remove the instrument cluster and place it on a clean workbench. Twist each of the illumination bulbs out of their sockets and remove the gauge securing nuts. Lift the printed circuit off the rear of the instrument cluster. Next, place the new printed circuit into position, securing it with the illumination bulbs and gauge nuts. Finally, reinstall the instrument cluster and reconnect the negative battery cable.
