Yesterday I took out the Instrument Panel and tightened up some screws and changed a couple of bulbs and today I noticed that my oil pressure guage no longer works. It just sits there at Zero and does absolutely nothing.
I checked all connections on the back of the panel and wiggled wires, cleaned terminals and cleaned the sending unit at the oil pan.
The idiot light comes on when I turn on the ignition and goes out when the engine starts so I assume that I have normal oil pressure.
Is there another sending unit somewhere? Is there an independent fuse? Also Is the connector to the guage on the back of the instrument panel a 4 pronged rectangular black plastic plug? I plug and unplug it and nothing seems to change on the guages so I assume it's the one for the oil pressure.
Thanks for any words of wisdom.
