99 GMC RPM GUAGE DOES NOT WORK

louzann7 · February 3, 2020

The RPM gauge does not work on my 99 GMC C25. Where is the fuse and will replacing the fuse fix it. The Tachometer seems to work.

The tachometer works, but the rpm gauge doesn't? wtf?

Do you mean the speedometer doesn't work?

The tachometer and the RPM gauge are the same thing FYI.

The cluster goes bad on those. You probably need a stepper motor.

Get the instrument cluster rebuilt with new stepper motors...common occurrence on 99-07 classic trucks/suv's

They're not stepper motors, but air core motors and seldom actually go bad (no real moving parts besides the needle itself). More than likely there's an issue with the truck farther upstream from the cluster, but it's not impossible for the motor to be bad. Be prepared to pay though if you attempt to repair it, as they run about $40 each for a new one, and then the calibration is a little more difficult than the '03+ clusters if you're doing it on a bench.
