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 3

Hazards have a different flasher than the turn signals. Make sure both front and rear turn signal bulbs are good. If one is burned out, that side might flash funny or not at all. If bulbs are good, then it could be the flasher. Usually the turn signal flasher is a small module about an inch or two in size, and located near the fuses or it might be under the dash near the steering column hanging by a couple of wires. Pull it out, bring to a car parts place to get a replacement, and plug it back in.

I agree , if it were only one area of error I would first and foremost say verify your temp with a point and shoot temp gun , but it sounds like you need new cluster , I'm sure the other Answer is also correct to re solder the components , but most just want it fixed quickly . I would also remove battery so when re installed your cpu re sets

i would check the oil pressure sensor

It could be due to the electrical board fuses going bad. I had to replace one for my odometer/gear indicator not long ago on my '98 Century. For some reason it's a common problem for Buicks. If you go to YouTube and type in "odometer repair" there is a video that will show you how to do it,if in fact that is the problem. But the gear shift indicator and odometer are all tied in to the same circuit. If you do try to fix,it really helps to have someone else there to hold the fuses steady whenever you are soldering the new ones in.

There isn't one. Computer controlled.

You will need to unbolt them from the floor, the nuts are under the car.

Check the hood latch and cable to be sure that they are not partially stuck and that the handle inside is not partially pulled and stuck.

Could be module and coils should be replace.

Are you sure it is all 4 wheels locking up? I have a 1998 Century and had the same problem, it is due to moisture getting on the rear brake shoes, this makes them "stick" to the drum cold and lock the wheels, the newer brake shoe friction material has been improved to avoid this so called "stickson" problem in moist cold weather.

Misfiring. Have the codes read. Code number p0301 is number 1 cylinder. p0304 would be number 4 cylinder and so on.

The park feature must be malfunctioning. The crank arm on these wiper motors is not solid.....they rotate on themselves......as they rotate around, there is a moveable "peg" underneath the arm.....when you shut the wipers off, this peg catches a "tab" that causes the arm to rotate on itself, and parks the wipers( the tab is part of the mounting bracket that the motor is attached to)......you have to bend that tab upward a little.....do a little at a time....check it out by turning the wipers on and off.....when you have it bent up enough, the tab catches the peg, and the wipers park themselves..... I find the forums very helpful: Wipers stop in up position Work Ok Car Forums and Automotive Chat

It sounds like your car has a bad thermostat that won't open all of the way. However it could have a bad electric cooling fan, fan relay, temperature gauge or fuse!

Here's a diagram to help you out

I changed the thermostat on my 96 century 3.1. Take whatever you can off to get to it. It's a really hard job for such a simple repair because of the nearly impossible access. I used a flashlight, mirror, stubby wrenches and my wife's tiny fingers. Also use a failsafe type thermostat, it's better to be stuck open than stuck shut.
