How to repair GM Instrument Cluster Speedometer Gauge Stepper

Chances are you need another speedometer, or send that one to a shop to have it fixed.

The speedometer in this truck is electronic, the needle is moved by a tiny electric motor called the speedometer needle stepper motor, a stepper motor is a DC motor than can hold one position rather than just rotate when power is applied to it. You will need to remove the instrument cluster from the truck and send it in to a Ford electronics repair center that repairs speedometers.

depends. newer vehicles do this just for effect, basically for you to go "ooooohhh" however with older vehicles ( pre 2006) this could be a code that the computer system is giving you, if the needle spikes all the way to the end of the speedometer/tachometer then back down to zero, its most likely effect. but if the needle spikes to 3 numbers (ex-90, 60, 30. then back to zero) its trying to tell you theres something wrong under the hood, could be as simple as a fuse or 02 sensor...

check the cable both end (speedometer to transmission}

the speedometer clusters go bad alot you can take it out and have it repaired or replace it and have it reprogramed

There is a vehicle speed sensor on top of the rear differential, this sensor is also for the anti-lock brakes. Sometimes you just remove it and clean it (it's magnetic) and may start working again otherwise you have to buy new. Yes, this sensor will affect the trany shifting.

A faulty vehicle speed sensor will cause this.
It's mounted on the back end of the transmission where the drive shaft slides into, near the top, it's just held in with a bolt, on the right side of the tranny, also has a wire connection.

Oh dear one of these problems. Sound like a loose plug or dirty connection in plug Very hard to find Start by checking battery and ignition circuit plugs and terminals Hope this helps Feel for you!

instrument cluster needsto be replaced. check with your dealer may be covered under an extended warranty
