There is not a single fuse for the fuel gauge , there are a few that power up the whole instrument cluster ! If there were a fuse out more then just your fuel gauge wouldn't work .You probably have a bad sending unit in the fuel tank or the stepper motor for that gauge is bad ! The thing to do would be to take to the dealer or some other capable ASE certified repair shop that has a up scale scan tool that can check codes in the instrument cluster ! Or you can take a chance an replace the instrument cluster !
Fuel Gage Inaccurate or Inoperative
Inspect for any stored instrument cluster Diagnostic Trouble Codes (DTCs). Are any DTCs stored in memory?

Go to Diagnostic Trouble Code (DTC) List/Type
Go to Step 3

  1. Install a Scan Tool scan tool.
  2. Turn the ignition switch to the RUN position.
  3. Establish communication with the instrument cluster.
  4. Select special functions under the main menu.
  5. Select output control under special functions.
  6. Select fuel gauge sweep test under output control main menu.
Does the fuel gauge perform a full sweep when commanded?

SOURCE: Heater/AC Fan does not work in our 1998 Buick Century

Fan will be under dash on passengers side , Removing glove box might be needed, Gm also uses a blower resister ro control fan speeds. First check your fuse and then check and make sure your getting 12 volts to the terminal at the blower, You could have a blown fuse, a bad switch, or a bad resister , if your getting voltage to blower motor then most likely it will be the motor. These are not to difficult to change. I hope this helps, please be aware I can only guess at what the problem is from my past experience.

SOURCE: 2000 Buick Century gas gauge reads full all the time

You're either looking at a short in the wire that goes to the fuel sender, or a bad fuel sender. If it was just a broken wire, it would read empty instead. The fuel sender is a permanent part of the fuel pump, so that has to be replaced as a unit.

SOURCE: 2000 buick century custom. fuel gauge fluctuates

The sender unit has a fine resistance wire with a slider to read the level, the slider or wires are worn and making intermittent contact, the low fuel light is a seperate switch so it will still work.access to the sender is usually under the rear seat cushon, under the soundproofing and a cover, have a look and describe what you have .

SOURCE: I have a 1998 buick century and the odometer and gear

This is a very common problem. I too have this going on. I found a Edmunds Forum and a poster has a fix, at least for him. Link: http://townhall-talk.edmunds.com/[email protected]@.ef22120/307#MSG307 and see if this is your problem too. I ordered a new headlight switch. Its an easy replacement too. Remove the left side dash panel, two screws and the 20 pin connector. Hope this helps.

Is there a fuel reset button on a 1998 Buick century in case of a front end bump


No. Ford is the only manufacturer that uses a resettable inertia switch to cut power to the fuel pump in the event of a collision.

Can't find the fuel gauge fuse what code is beside the fuse


there is not a seperate fuse for the Fuel gauge, if the fuse was bad nothing in the dash would work, you have most likely a fuel gauge sending unit problem.
