speedometer problem

2000 blazer zr2, the speedometer is stuck reading 110 mph with vehicle on or off. can i reset this or what can i do?

Hi, Have you receive a solution for your speedometer? I have a 2004 silverado extended cab and it does the same thing.

I'm not sure if the 2000 Blazer has this same issue, but the 2004 Silverado does.  My 2003 Silverado has the same problem. The problem is the small stepper motors in the instrument cluster that move all of the needles (Speedo, tach, gas, temp, etc.). If GM won't fix it for free, and you've exhausted all other avenues, you have some options without paying GM several hundreds of $.  If you're handy with a soldering iron, you can fix the speedo for about $12, and the whole cluster for about $75, or you can have someone repair it all for you for about $150. The problem is the same with several 2003 to 2007 GM vehicles: most trucks and SUVs, and some cars. See my post in another forum for more details: http://www.topix.net/forum/autos/chevrolet-silverado-1500/TR5QAB2MN19BL1D2J/p8

please share how you fixed the instument cluster, i have a 04 impala and all the gauges are not working right..

Mine does the same thing, but its directly related to unhooking the battery.
Get your safety goggles on. Take your negative cable off, make sure the needle is back to zero. If not, tap the negative cable against the post to slightly spark it (BE CAREFUL: batteries can explode) and then see again if the speedo is at zero.  If its not, connect the negative cable back to the battery and see if it goes back to zero. Drive it around the block and make sure the speed seems accurate, if you can't tell exactly how accurate it is, have someone follow you. If its not accurate, repeat the process again.

You may want to try the battery trick before you go spend money.
