If the speedometer stopped working on a 1990 Cadillac Seville, it could be the fuse or an electrical problem. First check the fuse and if the fuse is good, check with a mechanic.
If all the gauges in the clustor are working and only the speedometer is not, I suspect the Vehicle Speed Sensor which is located in the transaxle. Easy to replace and only about $15. http://www.partstrain.com/ShopByDepartment/Speed_Sensor/CADILLAC/SEVILLE/1999
either one or both of the following causes that. 1. the instrument cluster is bad. 2. the body control module is bad. both are junkyard parts but the trick is finding good ones.
I have a 1992 cadillac seville. The window won't go up. The window motor is working. I want to see if the glass window itself is off the track. How do I remove the inside panel of the door to get to the glass window?
The speedometer and odometer may stop working in a Nissan Pathfinder due to an electrical short. It may also need a new spark plug.
This is a 1998 too by the way
If the speedometer/odometer is working, chances are the VSS (Vehicle Speed Sensor) is good.
Is this a statement or a question
speedometer not working can you help
If the speedometer and brake lights aren't working then you should change the fuse. If that doesn't work then check the electrical system associated with your Heritage.
you can go to speedometer and out of speedometer
You may need to replace the speedometer fuse. The speedometer cable can cause your speedometer to stop working. The speed sensor can also cause the speedometer to stop working.
My 97 had the same issue. The relay box went out and the relays were still good. It should be on the driver side fender wall.
