Speedometer wont go back to ZERO, what should i try to fix?

You need to grease the speedometer cable

speed sensor on the transmission

Try giving the gauge pod a solid hit with your hand. This may jolt the needle back.

Otherwise,

• remove the gauge pod.
• remove the front clear panel from the pod.
• move the needle back the zero position.
• reassemble.

See if the speedometer now works.

try physically pushing it back to zero then drive the car if noting happens the speedo is bad

Pull the rubber trip reset pin out slowly so all you see is the hole & the shaft. Take a long tin-tie (about 5 inch) & fish it inside the speedo to the needle & carefully bring it back counterclockwise when its back at least to "2-3 O'clock" hold it & turn your switch to coil...the needle will go back to zero. keep the tin-tie in your coin box if ever it happens again!

sounds like you have a bad speedometer cable - these will make the numbers 'stick' because the cable slips --

Also - take down the vin number and call the local dealer - ask about any recalls or service bulletins

Pretty common problem with these. Here's a guide to learn how to fix GM instrument clusters yourself, I used it to fix mine and it worked great.How to guide for Silverado instrument cluster repair

you may have inadvertantlly disconnected the speedometer cables or have them loose

Take your truck into a Chevy dealer. There is a special poicy for 2003 trucks with this problem. They will replace the ipc cluster for free.

"The Fix" works...I would have not believed it untill I did it.... Start the car in reverse and about 5 times later it reset the speedometer back to zero.....wow!
