Morning all, my temp guage is not working and dash says check guage. Replaced block sending unit twice and still nada? Could the guage in the dash be bad and if so can i get it through dodge or do i need a whole dash ***.?

never been in one to say for sure, but I think you need the whole dash, i have had the cluster block out and all that is on the back it a big circuit board

what year is it?
