      The gas gauge works fine until it gets down to about 1/2tank then it jumps from full to empty and doesn’t run properly.

      RE: The fuel level sensor inside the gas tank, which is attached to fuel pump assembly has become worn out. What happens is, over time the fuel eats away at the little metal ‘fingers’ that slide back and forth on a resistor board which tells how much gas to show on the fuel gauge. Once these get worn enough, the gauge will start to act funny, be erratic, drop from full to empty at times, etc. What you need to do to remedy this problem is to replace the fuel level sensor. This can be purchased separately from the fuel pump assembly, but you need to drop the fuel tank out of the vehicle and remove the pump to change out the level sensor.

      Worn out fingers on the fuel level sensor causes the gas gauge to be erratic.

      I have a 2000 Buick Regal and the dashboard is kind of crazy. The lights are out where the gear shifts and mileage are and also the gas needle reads are  inaccurate. What might that be? Also the panel where you turn the heat and a/c on does not come on when you touch the power. What could that be?

        REPLY: Sounds like you have several problems on your Buick. the gas gauge not reading coorectly is usually the level sensor in the furl gas tank. The speedometer and odometer not reading is ost likely aproblem inside the dash, and it would need to be repalced. The heater and A/C controls are probably not related. check all your fuses first. If goo, then the control panel may be bad, but you would need some circuit testing to be sure.
