My speedometer works but odometer does not what should I look for.thanks in advance
If your speedometer works but your odometer does not then you have an internal instrument failure. You will have to remove it and get it repaired or purchase a used one (possibly on eBay) and use that.
I had same problem, got mine working.
Remove cluster, remove speedo.
You’ll see a cylinder shaped thing (motor?) with blue plastic worm screw on the end, which turns the odometer gears. There is a clip that holds it down, remove that and you can lift cylinder out.
I dripped some silicone spray down it’s shaft, and turned the little blue gear by hand back and forth a TON.
While cylinder thing was removed, I also spun odometer gear for trip odometer, which will move forward main odometer, a good 50 miles to make sure it rotated smooth.
Put it all back together, and odometer started working again.
