My 1991 New Yorker with digital guages have gone crazy. The speedometer comes and goes and voltage will disappear all together. sometimes temp will act strange as well. Im assuming its the Logic Modual cause it dosnt do this with another logic modual i have. I wont use that modual because it does not show miles or my fuel readout display. Do yall know of anyone that can rebuild this modual. The dealers are no help. A1 cardon no longer manufacture them.
