I just bought a EX gauge cluster real cheap because the fuel and coolant gauge did not work. So I went to a friends house and he had a gauge cluster but the tach was broken. But I wanted the fuel and coolant gauge and it was working at his house (We tested it out on his sisters civic). I took the fuel & coolant gauge off and put it on the EX cluster I bought and the fuel is always full and the coolant will not move. And if I move the screws around and then they both go up and stay up.

Help what wrong is this fixable or should I buy another gauge cluster HELP ?

 

Sounds like something is wrong with your cluster and it's circuit board.

Buy another, or use your buddy's.
