The problem may be in the wiring from the power source to the Instrument Clusters connector. Check continuity of all wires at the connector and at the Bulkhead connector (firewall). If all of these are ok, I would suspect a defective printed circuit board on the cluster.
could there be a relay and if so how do i check not in manuel
