on the instrument panel everything works exept the rpm and the clock which they are attach together

clock dosent work so i dont know if that might be a clue if the rmp gauge is nor working

if any body have any clues of how to fix this problem , please let me know
all fuses are find , i look them and test them with snap on test light
