There is not a cable for the speedometer. The information is sent to the gauge cluster from the PCM. The PCM controls almost all aspects of the vehicle operation. All of the information on the gauge cluster comes from the PCM.
Remove instrument cluster in a 2003 olds aurora
2003-2008 located in the dash cluster by your speedometer. 2009 On the information cluster above the radio.
the dashboard cluster could have broken. That happened to my 2004 trailblazer and I had to get it replaced
If the speedometer is not working but the odometer is, I would suspect the dash cluster is at fault. If both speedometer and odometer are not working I would suspect the speed sensor on the transmission is at fault.
If both the speedometer and odometer stopped working it is probably the speed sensor in the transmission gone bad. If only the speedometer quit you may have to replace the dash cluster with a reconditioned unit.
You can't you have to replace the whole dashboard instrument cluster assy.
you need to replace dash illumination bulbs only problem the speedometer cluster has to be removed
If both the speedometer and odometer are not working I would suspect the VSS (Vehicle Speed Sensor) is at fault. If the speedometer doesn't work and the odometer does, I would suspect the instrument cluster is at fault.
Have your mechanic check the speedometer cable connections. They no longer use a cable. It is electronic. If the speedometer is not working but the odometer is, the problem is in the dash cluster. If both the speedometer and odometer are not working, the speed sensor in the transmission may be at fault.
could be a bad instrument cluster panel, they had a recall on the instrument cluster panel. I had my speedometer stop working and was given a price to fix it and blew it off. Then the recall came and I got a new instrument cluster and that fixed the problem which they knew they had.
It shouldn't have one. The speedometer should run off a signal from the vehicles computer.
