I have to change out my cluster but getting all kinds of different info as far as getting it cloned/programmed for my car to even start again. My dash lights blink warning lights come on randomly and my odometer went blank along time ago. Maybe 40,000 ago. A mechanic told me I needed a new cluster which is discontinued (1998 LS 4.3 rear wheel 4 door) and quoted my $340 for remanufactured and $110 for labor. I can do it myself but don’t believe they are plug and play.

 

I was able to replace my instrument cluster in my 1999 from one I got from a wrecking yard with no problem. I simply plugged it in and it worked.

Not surprisingly the odometer was off. I just recorded the difference in my maintenance record notebook.

 

Wow that simply? What about codes already in there? What about the fuel gage? I heard these would all be an issue

 

Yep. That is all I did, pull out the old one and plug in the new one. I had to do it because the stepper motor for the speedometer gauge was sticking.

And if you shop around, it is possible (from what I've read) to find OBD readers that can reset things like the odometer.

I believe all the data will be stored in the ECU or BCM.
