So driving to work this morning I noticed my speedometer was stuck at 60 no matter what speed I was doing. All the other gauges were working fine (tach, etc). Odometer was working too.
When I got to work and turned off the truck it still stayed at 60 (see pic). When I got back in the truck to go home and started it up it was sitting at 50.
Driving on the highway it would go up to 110-115 (I was going along with traffic) so I figured I was really going 60-65. Pulled in turned off the truck and it stays at 50.

Is this a mechanical issue or something else? Would unhooking the battery help any? Any help is greatly appreciated as I don't want to take it to dealer and have them charge a ton of $$ if it is something I can fix.

you can try a gauge sweep and see if it re-calibrates. Cluster problems are common on our year truck 04-08.

 

I can’t answer your question/problem directly, but have a couple ideas to possibly try or look up more info:

- disconnecting battery s/b easy thing to try with no downside risk

- there is a way to make a cluster go through a test sequence that includes cycling all the gauges. I’d try that. Don’t recall exact term of procedure, but I’m sure you can google/YouTube it. I think it’s one of
the things where you push this, push that, cycle key five times, etc to get to test cycle. Maybe someone else will post back with more help on this.

- you could remove this and send out for repair (several places offer the service). YouTube will show you how to remove. It’s not that hard (I did it to replace odometer light bulb)

- if it wAs me I’d consider eBay/junkyarding a replacement cluster to use while yours is out for repair

good luck and list back with how it comes out. You may need to spend some time/money, but you definitely don’t need the dealer to resolve this.
