Speedo and fuel gauge replacement

A speedometer shop can test and repair your head. Your fuel gauge needs further diagnosis to determine where the problem is. Guessing gets too expensive. When the cluster is on the bench, power up the printed circuit board and ground the sender side of fuel gauge. This should peg the gauge to full and eliminates any wiring issues. If this does not peg the gauge, then you have a bad gauge. There are people that can repair these or you can buy a used replacement.
