Not sure if this is the problem,and I dont have my wiring diagrams handy. There is a fuse in the left hand side of the panel . remove the cover and there is a fuse diagram there look for the ode fuse its under a special cover . If its blown it effects lots of things . Hope this helps.

Either that, or a couple of wires have rubbed through.

took off the cluster and cleaned the two harness on the back w contact cleaner but they looks very good... w the cluster in position sometimes it illuminate and sometimes not; if I move it a bit it illuminate and function good for a while... maybe its a contact problem on its back... pins and harness looks perfect. . I've noticed, w the engine off, that when I turn on the lights, and cluster not illuminate(both LH and RH turn signal lights on and flashing intermittently) I hear a bad noise from thre engine bay... like a relay that engage and disengaged continuosly, its the fuel system relay under the fuse box in the engine bay; and even the "valves"wires/connection bolted to the inner LF fender, under the left battery, I think its the stuff for the heater grid(cables goes onto it)... but I dont know what that concern w cluster illumination...



I need help, thanks
