The dealer has to program it.
Replace the instrument cluster.
If the speedometer and the odometer are not working, I would suspect the VSS (vehicle speed sensor). If only the speedometer is not working I would suspect the instrument cluster has problems.
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.
You have to take apart the instrument cluster, starting with the steering wheel and working forward.
If the speedometer and odometer both quit I would blame the speed sensor. If only the speedometer quit I would blame the instrument cluster.
when that happens you usually just have to replace the instrument cluster when that happens you usually just have to replace the instrument cluster when that happens you usually just have to replace the instrument cluster
Why is your 97 cadillac deville instrument cluster not working?
You need to determine if it's the speedometer itself that's faulty, or the vehicle speed sensor. If the speedometer is faulty, you'll need to replace the instrument cluster.
It doesn't have one. It uses a speed sensor and drives the speedometer electrically. If your speedometer isn't working, it could be the sensor or it could be broken solder points on the instrument cluster circuit board.
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.
We had the same problem, and our 1998 F150 needed a new instrument cluster.
Most likely because your speedometer cable is broken. If I find the guide for removing the instrument cluster, I'll post it here.
