Saw this on my way to work today. WTF? Seams to be working good, maybe just the gauge is bad?

Typical problem in this era trucks. I just replaced the stepper motor on the speedo on my '03 2500HD, it got notchy and then stuck at 25 (when stopped it read 25, then always 25 higher than actual). All the gauges use the exact same stepper motor that is soldered onto the back of the circuit board. It cost me $6 for a new motor of eBay and it's pretty easy to pull the cluster apart.
 
Mine the trans temp doesnt light up and the shift indicator is black, the amp guage read lthe same as the one above for about ten miles a year ago and has been fine ever since. i guess ill be looking for a cluster. Does the dealer have to program it for the new cluster..?

Any more info on pulling that cluster? My 03 Silverado speedo is flaky and I have been thinking about fixing it. Dealer wants a boatload of money to fix it.

There are all types of write-ups on the internet as this is a pretty common issue. Here is the first one I came up with when doing a search and it seems pretty consistent with what I did.

Do a search on eBay and there are about a thousand people selling the stepper motors. Look for GM stepper motor, believe the new p/n is X25 168. It cost me $6-something to have on shipped to my house in a couple of days.

The hardest part was setting all of the needles back correctly. Before pulling the needles put a piece of masking tape under them and make a mark. It's pretty easy to turn the shaft of the motor a little so you they may not be in the right place when reinstalling. I kept the face off the cluster and readjusted them as needed. I think all of them are pretty much at "0" with the key off so I set them at that point and then drove some. I had a GPS to verify speed and knew the rpm at that speed (65 mph down the highway). Also knew what the charge, engine and trans temp, and oil pressure were when warmed up and cruising down the road so I had a reference to make sure they were correct.
 
Hey mine looks like that too.....I think my truck is possessed gauges randomly go all over the place, the red light on my 4x4 switch goes on once a month but it still works like normal. Half the dash and radio lights are out, my drivers seat back and forth switch is reversed, the heated seat has been known to turn it self on and last but not least......about a quarter of the time when I turn on my foglights, my rear wiper makes a pass.

I think the 03-05 have gremlins in them.
