Speedometer/odometer not working

Hey new to the group.

Speedometer and odometer not reading. Wouldn’t start randomly. Turns out there was a short by the starter, so got it fixed. I had replaced the ignition switch before finding the short.
It’s running again but speedometer and odometer isn’t working. Everything else on the cluster is good. Any ideas?

Welcome to the forum from Oregon.

Did the speedo and odometer work before the short repair near starter and ignition switch replacement? You did not say.

My bad, yes it was all working good.

The obvious next thing to do is to check your work. If ignition switch was replaced first, how much time in between when the short was fixed? Did speedo and odometer work after the ignition switch and then stopped working after the short fix? These details would help.

Welcome!

Do the other gauges and dash lights work? I was thinking maybe the plug came out of the instrument cluster or something similar, when you were replacing the ignition switch.

Perhaps a moderator will move this out of the ENGINE section and into OEM + Custom Interiors.

Did you have any luck in figuring out what was going on?

I have the same problem. All gauges work, but no speedometer or odometer. Did you find a solution?

After a couple weeks, random day just started working out of nowhere. Sorry I don’t have much of an explanation

My '88 did the same thing, on and off for years. Turned out to be a faulty DRAC module in the instrument cluster. I think your DRAC is free-standing somewhere in the area of the glovebox.
