Could be some electrical gremlin here!

I pulled off the connector to the oil sensor at the oil pan and the windshield washer warning light came on. I tried jumping the sensor directly to the 4 connector pins to the back of the cluster. Other warning lights would go on but the gauge was still dead. Maybe the gauge is just "DEAD!" I am not aware of any "FUSE" just for the oil gauge. All other gauges and lights work OK!
