i swapped my old EX cluster out for a GSR cluster. I had to cut the EX harness to fit into the GSR cluster. I then decided to use my old EX cluster later on, i put all the wires back together and it worked great....then i decided to get glow gauges, put those in and also was fine, until one night when i was messing around with the wires in theback of the cluster, and then the dash lights and cluster lights went out. i checked all fuses and were fine.
when i take the interior light wire on the cluster and put it to ground, the heater control lights turn on, but not my cluster lights, i don't really know what's going on, i think it might be a bad switch, but not 100% sure. i can still see my cluster because of the glow gauges, but it would be nice to see my heater controls and my milage on my cluster? could i have blown the bulbs in the back of the cluster or the whole cluster itself is fried?

any suggestions or comments would be great....

thanks
