How do I repair or replace a defective gas gauge?
It is in the instrument cluster, which has to be removed to replace the gauge. It cannot be repaired. Did you first check the 10 amp METER fuse in the fuse panel?
Now let me say, that when the gauge quits, it is more often a fault in the sending unit in the gas tank, and not the gauge. Here is how to find out if your gauge is good: Find the fuel tank electrical connector, and pull it apart. You will need a small jumper wire. Find the blue wire in the body side of the connector (not the fuel tank side). Put the jumper wire into the blue wire terminal, turn the ignition key to on not start, and ground the jumper wire to a metal frame piece. Someone needs to watch the fuel gauge needle while the wire is grounded. If the gauge in the dash is good, the needle will move. It will probably go to either full or empty, but if the needle moves, the gauge is good and the fault is in the sending unit in the tank. Don't give up testing until you are sure the jumper wire is being grounded good to the frame. Just touch the wire to frame and watch the needle movement, once sure, stop so you don't blow the fuse. If the needle doesn't move, first check the 10 amp meter fuse. If fuse is good, it must be the gauge.
