1999 Express Speedometer Sticking
My recently acquired conversion van with 38,000 miles has a sticky speedometer. Sometimes high, sometimes low and sticks momentarily on the way up and down. Is it a bad gauge or is there a sending unit on the transmission that controls this?

Plug in a diagnostic scanner and go for a drive.
If the speed on the tool is normal, then the problem is your cluster. If it's not then it's the sensor.

I did a 2003 Trailblazer and it was easy if you can solder. I replaced all 6 while I was in there. The 1999 is a different stepper motor and I am not sure how easy it is. They are available on Ebay and you can look to see if Youtube has
a video on how to do it.
