RE: 6.5 diesel

do u have the digital odmeter on u'r dash ???? if so there was a reprogramming TSb on this unit ,, i could go into the technical side of it ,, but Nash would not understand it :laugh: bty ,, i would ck with Chevy on this due to the fact that u might have a bad cluster board and maybe the programming won't help ,, but ck into it ,, and post us back :approve:

Oh yea welcome to the forum

Hey Whisky6 now with that handle I could think of a lot of problems but wont go there. Not starting out with ice on the road are you :laugh: :laugh: . I will go along with 730 on the chevy TSB because there was one on the digital odmeter even though i can't figure out how he knew that :laugh: As you can see we get around to answer :question: sometimes welcome to the forum

Re: 6.5 diesel

Those clusters were all electronic, I had 4 trucks with the same cluster in it and had to have 2 replaced because of elec. problems. Maybe in the cold a "not so great solder joint" is acting up. Also a little moisture could cause problems.

Re: 6.5 diesel

Yeah, move to WEST Texas! No moisture problems there! :clown:

(And yes I'm riled up because 730 has Aldata hid away in his garage and didn't tell nobody! )

Those kind of clusters are more just displays, because the main computer program is running them based on sensors hooked to the computer for ignition etc.

I'd say if the digits show and adjust with speed, then the problem is in the computer. There's a computer reset coming, I'd bet.
