Cadillac 16218496 CLUSTER

In case of failure of the speedometer, then check up the speed sensor pickup and if faulty, replace it. Check the connection between the speed sensor and speedometer/odometer wiring for bad terminal connections, poor connection points or broken wires, and correct as applicable. If in doubt, fit a known working speedometer to check the car's operation; replace the speedometer assembly if it works as expected. If a car speedometer is intermittently working, inspect the wire harness between the speed sensor and the speedometer, and check its terminals for signs of corrosion, connection looseness, or broken wire; if any of these is present, it has to be cleaned or repaired appropriately; further, if the relevancy of the speed sensor pickup fails to work as is expected, it has to be replaced.

You can get to the instrument cluster by opening the rear end of the instrument panel in the center above the steering column. The instrument cluster sits above the steering column and shows the driver how well their vehicle runs. If you have to replace the instrument cluster, you must either move the odometer reading from the old unit to the new one or hang a label on the driver's door that tells how much the car had traveled before and when that new cluster went in. Before you can remove the cluster, do two things: disconnect the car's battery cable first, then remove the upper trim panel by taking out the A/C plugs, unscrewing hidden panel screws, and then screwing the defroster outlet away. Disconnect by peeling away two wires that connect your car's sensor for temperature and its replacement air system, and if needed, take off the sun panel detector. To take out the instrument cluster, start by removing the upper trim pad. Then take out the screws underneath the pad and the plate holding the cluster in place. Remove the screws that attach the cluster, carefully label and detach the wiring connectors, and take off the shift indicator cable clip. To put back the instrument panel, place it in position, hook up all electrical connections, put in screws, and make sure they're tight. Reattach the upper cover plate, then put back the shift indicator cable clip. Adjust the shift pointer to match the N mark when your gearshift lever sits in that slot, place the cable correctly on the bowl, and make sure everything looks right as you move through every shift position.
