Q: How to remove the speedometer and gauge clusters on Oldsmobile Cutlass?
A: The Speedometer and gauge clusters on the models from 1974 to 1977 can be independently removed for maintenance. The process of doing this starts by entirely disconnecting the negative battery cable. In case your vehicle has an automatic transmission, you will have to detach a shift indicator cable from its shift bowl. Afterward, extract the three attaching screws and pull the cluster far enough to separate it from other electrical connectors. Finally, take off the cluster itself. For those cars produced between 1978 and 1980 all gauges together with their speedometers are taken out as units. Unscrew this pad assembly firstly after disconnecting negative battery cable, then remove the steering column trim cover. Meanwhile unsnap release tab for gear display clip (shift indicator) on steering column bowl so that you can then pry off the four screws mounting cluster into panel adapter.Remove instrument cluster assembly by pulling it outwards to facilitate disconnection of Speedometer Cable as well as wiring before removing it completely from car.
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.
