06 duramax speedo?

do you have the digital odometer,or the manual of,if manual check the gears on the end of the cable,you will have to pull it out of the tranny,should ge one 10 mm bolt with a u brace to remove then pull out cable.

ur gauge cluster is bad

if gaudge cluster was bad nothing would work.

yes they do on chevys and gmc's! ive replaced 2 of them on my 04 and everything worked but the speedo and the trans temp gague!

you get yours out of junkyard,go to school.

Stepper motors are going bad. Had the same thing in my 2003 Silverado. Here are directions on how to fix. http://usedcarsit.com/content/chevrolet-speedometer-gauge-repair-instrument-cluster
