'89 GMC Odometer not working

25688 Views 4 Replies 5 Participants Last post by  Bryan Carosi
I have seen some other postings about odometers not working on newer trucks and how the instrument cluster is all one unit. I am hoping that with mine being a little older the odometer can be fixed without having to replace the entire cluster. Any suggestions? I am hoping to try to fix it when I dig into the dash to change out a burnt out dash light.

Once you get the cluster out, you can remove the lens and the rear cover by removing the screws around the perimeter. My old '91 had the same problem and I found some broken plastic in the odometer, which caused it to quit. I was able to re-work it with some metal strapping and a small screw or two. As I recall, it was the retainer for the spring on the reset button and it went together pretty easily. I hope yours is just as easy.
Good Luck and God Bless
