Easiest way - You can connect a good battery to your car (borrow a friend's) - if it cranks over and stays lit - it's the battery. When it is running on the friend's battery - use an Amp meter to tell if the alternator is generating any amps. Just stick the probes up to the wires on the alternator and see if the meter moves. If it doesn't move you need a new alternator and regulator.
Amp meters are cheap and you can get one at Radio Shack.

The fuel filter is located underneath the car in front of the gas tank.
You have release the fuel pressure. Remove the fuel filler cap, locate the fuel test port on the fuel rail on the passenger side on the end of the right real fuel rail for a 3.1L engine.

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: 91 Buick Century 2.5 L brake light on & battery light on

For the Brake light to stay on and the fluid is up...sounds like your sensor is playing dead......

For the battery to die after only (4) hours..you have a very big drain on the battery itself.....without the vehicle right here to look at would be very hard to even guess...electrical problems are a hands on chore...

I'd take it to your garage/mechainc

1991 buick century battery light on


Charge your battery and have it tested. Most part stores will do this for you at no cost. I'm leaning towards an alternator issue but it is possible that it could be both the battery and the alternator. Even if it's just the alternator the battery should be fully charged as a discharged battery can damage the alternator.

Don't have any electrical power bought a new battery the alternator seems to be ok but there is no lights no anything we check the fuses in the dashboard nothing seems to be blown what can the problem be?


The battery post connections are critical, and need to be clean, and snug...have you tried to jump start...and does the battery connection spark when connected? Sounds like a bad or dirty post or fitting...hope this helps...:)

1998 buick century-electrial all work but when turn key like dead


Sometimes there will be just enough corrosion on the battery terminals to allow for low draw items such as the radio but not enough contact for the most heavy draw item, the starter. Start by cleaning the terminals. Also jumping of another car to the battery cable ends will tell you if the terminals connections are compromised.
