speedometer stuck on 25mph and just goes up when driving not actual speed of course, so is this a easy fix or do i just have a shop do it?

Sounds like you need a new speedometer cable. You have to remove the instrument panel as one end of the cable housing goes to the back of the speedometer. The other end of the cable housing is attached to the transmission. Once both ends of the cable housing are detached you pull the actual cable out of the housing from the speedometer side. Installation is fairly easy unless the cable housing has been damaged. You just slide the new cable in and re-attach them and put everything back together.

I had one that quit working and was going to replace the whole cable but when I detached it from the transmission I found the gear on the end of it was bad. It was made of plastic. I just bought a new gear and replaced it and it worked. There was one bolt that held cable into tranny and a c-clip that held the gear on. Simple.

Are any of your other gauges malfunctioning? This is a HIGHLY HIGHLY common failure of the IP (Instrument Panel) in larger GM trucks/suvs. Not a cable, nor a sensor, but the cluster it self, which MUST be serviced at the dealership due to the cluster containing the mileage, digital clusters on GM store it in the cluster, not the body controller or engine controller.

Also, from what I remember, these trucks do NOT use a cable, they use speed sensors located in the transmission, or on the differential.

If GM/Chevy wont do anything for you, look at sending your cluster off to either Technicar or Specmo. (Two companies a GM master mechanic I know recommends, among others. YOU CAN NOT GET A JUNK YARD CLUSTER, IT WILL NOT PROPERLY WORK IN YOUR TRUCK AND VIOLATES SEVERAL LAWS!!!

Thanks everyone! It started to work again, so I'm hoping it will hold out until maybe this weekend so I can just take it in thanks again.

If it is sporadic, I would check for corrosion at your electrical connections if you can, believe it or not mechanics use weather to help trouble shoot these problems. Such as, was it raining around the time this happened, or did you go through water, and so on.

But yea, check your battery cables, fuses and so on for signs of corrosion.

 

[techleaner]

Will do, now that I really think about it, it happened in the sudden change of cold weather. I was running late for work so I didn't really give it time to warm up. Not a mechanic so not sure if that had anything to do with it lol.

Yea, check for corrosion, seems GM trucks AND cars are very sensitive when it comes to clean power, a bit of corrosion on a cable, or data link connector can throw off just a single gauge in your cluster, also check your VSS and other sensors on the transmission if you feel upto it for corrosion.
