Hello, I have a 97 mustang and here lately the temperature gauge, gas gauge, and rpms will randomly quit on me. After driving for awhile they'll usually slowly start to work again, but its starting to happen more and more and taking longer to come back. Any ideas? The other gauges are fine and haven't had an issue. Im relatively inexperienced so I figured I'd get some opinions before throwing money at it.

 

jasper_roberts99, I'm thinking a ground strap/wire is working loose. These three gauges probably have a common/shared ground. Locate the ground wire and make sure the grounding location is clean, also clean the "eyelet," and then reattach the wire to whatever it is attached to.
