I have an 04 Suburban Z71 4 X 4, I have recently had all of the stepper motors replaced on my cluster, they all work fine now, except my oil pressure gauge. It jumps all over and chimes all of the time. My oil pressure has been checked and it is fine. We recently replace the sending unit to stop the oil pressure chime, but this did not fix the problem. Any one know what could be causing this annoying sound?
