04 speedometer troubles!

[89 crew]

Hi everyone, I'm having some troubles with my 04 1 ton crew cab 4x4. Yesterday I was driving in the driveway and the speedometer stayed at 45 mph. I shut it off, no difference. When I restarted it, it dropped to 35. I took it for a drive, and it stuck at 40 when I slowed down. It seems to be close on reading after I go faster than where it stuck at last time. I don't know if it could be a ground, the speedometer is toast, or what to look at. I did crawl under and check out the loom and didn't see any connection problems or damaged wires. Any ideas you have would be appreciated!
thanks

It's probably the speedo itself. It seems to be a common problem that the gauge servo's go bad. Take a look at ebay. There is a guy selling rebuilt cluster there with improved servo's. That's probably the best route to go.

to get it back to zero, turn the key to on, then back off. It will come down a little bit at a time. They do have a tendency to stick. I second teh rebuilt cluster idea.

Delphi had a major problem with the speedo motors in 2004. I would recommend contacting the AC Delco instrument repair center below to either have them repair yours or exchange it.

If you have less than 70,000 GM will replace it free of charge. Go see your local dealer service dept.

I have the notice on my 03 GMC and it states exactly that! The warranty is extended on the gauges ( speedo, fuel, etc) to 7 yr 70,000 miles.

that warranty extension is only on 03/04 models, but i will say at the dealership i work at we replace about 4 instrument clusters a week between me and the other chevy mechanic, ranging from 2002s up to 2006s.

per GM service info:

If it's not one of the models covered under the extended program the service manager can also "A authorize" the repair and get it covered for you, if he wants to

Thanks everyone. I talked to the dealership I got the truck from. before I did I did a search online. It turns out the reason they have the program for the 70000 miles is a class action law suit. at first the dealership didn't want to do anything besides charge me $350 for the cluster + labor to fix a truck with approx 40k on it. So I asked the service manager if I needed to join the class action law suit before they could take care of this problem. Ya know I have NEVER seen anyone change their tune so fast. Soon as I mentioned it they were happy to take care of this problem at no cost! I took the truck in yesterday for them to get the hours and miles. I'm suppose to take it back next week for the new dash. They are replacing the entire unit because the other gauges tend to go out shortly after the speedo. So once again, thanks for the input. This problem is solved!

[N2TRUX]

Wonder if I could get my 05 with 80k miles on it covered?

[89 crew]

Well everyone I took the truck in for the dealership to install the new dash today. While I was there they told me the dash problem is now going to be a full recall for 03 and 04 trucks. Since the 05 and 06 use the same cluster the rest should be coming soon.
