I was driving I-70 the other day, looked down and noticed that my speedometer showed well past 120MPH when I obviously was not going that fast. I pulled over, stopped the truck, and my 0 speed was shown as 90MPH. I turned off the key thinking that the system would reset, and when I turned it back on I seemed to gain back about 5MPH, so my 0 speed was now shown as 85MPH. Over the next few days it eventually got back to 0MPH through normal usage and it's been okay since. I recently when on a long trip that was about 90% cruise control and had no problems. Any ideas what the problem was and my chances of having this recur?

Replying to: jmaher (Oct 27, 2006 3:29 pm)  The dealer told us that it was the motor in the panel and the panel would have to be replaced. At the same time we where having problems with the AC/Heat fan control (wouldn't work on 5 occasionally) and was told there was a short in the Fan Control Module. Total repair bill for both, $649.02. GM Service told me that I have to pay for the repairs as I'm out of warranty. Thing is, I've had it in to 2 different dealers on 3 separate occasions for the fan and they couldn't find the problem. Now that I'm out of warranty they won't pay for the fix. Convenient, huh!  Speedometer fails at near 50,000 miles and they don’t take responsibility let alone failures during warranty. Criminal. They know there's nothing the average Joe can do. My suggestion, save your self the aggravation and buy something other then a GM product.

Replying to: manda2 (Mar 09, 2007 9:19 am) Talked to a guy that used to work at the Chevy service department and he said that it was a common problem with 04 Chevy's. The speedometer cluster can cost between $300-500 to replace. The cheapest I've found online was between $175-280 (doesn't include labor). I've been searching online to see if it was a recalled product but haven't found any info yet.

Replying to: goodgirl71 (Apr 13, 2007 12:10 pm) I have since lost my RPM too. There is NO recall on this item, and yes, the cost is $300-500 depending on the dealership. I have driven many cars (and Chevys) and have never seen the issues I have seen with the newer model trucks and SUV that Chevy is producing. It is a tragic disappointment to our American Made motor company that is going to cost them dearly in the long run....  Not a fan of Ford here but at least they acknowledge and correct their errors....Unlike Chevy.

in response to speedometer cluster problems, it seems to be a big prob with chevy trucks & suvs. The prob is a stepper motor that is behind instrument panel, one for each needle. I fixed my own cluster with one i bought on-line for about ten bucks and a soldering iron. The guy will also rebuild it for you if you aren't confident to do it yourself. Look under "stepper motor for (your vehicle)speedometer cluster"
