Q: my rpm x 1000 gage is stuck on 7 and wont go back to 0

That might be a stepper motor failure. The gauge pointer is electronically controlled by a stepper motor. The stepper motors are soldered to the instrument panel circuit board and can be unsoldered and replaced. You can do it yourself, hire a mechanic, or send the whole cluster out for repair (search Internet for "GM cluster repair" and you will see shops but choose wisely). Obviously, before condemning the cluster it should be diagnosed to make sure that the failure is not in the wiring or the sending unit. To obtain that diagnostic, and also obtain further details on your repair options, just request an electrical component/circuit diagnostic. If you request that service, the responding certified mechanic will get this diagnosed and resolved, right at your location. If you have further questions or concerns, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you to get the best possible results.
