Need input what buick all are elect controled could be anything from bad VSS to bad speedo head broken wires the only relativly inexpensive thing being the sensor the head has to be sent to GM for repair(or one of their contractors) wireing could take 10 min to 20 hrs to find just depends how lucky sombody is. Run ALL fuses also.

Hate to tell ya but the only way to determine if you have a bad VSS (Vehical speed sensor) is to have it hooked up to a scan tool with live data capabilties and drive it if the sensor is reading. Then its the head unit aprox 580 with a tach 560 without and about an hr and a half job to replace.If the vehical is running and driving ok just no speedo or stuck in one place then my bet is on the head being bad. Sorry to be the bearer of bad news but the sensor is still a possibilty.

Have my buick at an independent garage to check out the speedometer. They said it was the stepper motors. It was late in the day so I'll find out Monday what they recommend.

How do you remove the stepper motors and what is involved to replace or repair?

Thanks

The DIY'r can't do it I have to send the instrument cluster to a Rebuilder in New York due to odometer and speedo programming issues I suspect the Feds are involved also to assure no "rollbacks" occur.The last one I had done ran about 550 to 600 including shipping.

Maniac, can't you also check the VSS by trying to engage the cruise control (if equipped)?
