I start the car and everything looks good. I drive 10 feet and the ABS and Brake light come on at the same time. I replaced the "ABS CONTROL MODULE UNIT COMPUTER" that was under the dash by the steering column but that didn't work. Brakes feel firm and strong. Breaks well. What next?
View 19 RepliesDoes this mean I need to see a mechanic. My car is a 97 buick century, 94kmiles. Rear brakes were replaced at 83k and front brakes were replaced at 80k. A few months ago, the noise began and has persisted once a day when brakes are applied first time of the day.
View 5 RepliesCurrently I have a 1998 Buick Century Custom having turn signal issues.
The front left blinker is not blinking. Understandably, with this malfunction, the rear left blinker blinks rapidly when the turn signal switch is in the left turn signal position. However, when I put the hazard lights on, BOTH rear blinkers blink normally as does the front right blinker.
When the headlights are on, the amber-colored blinker bulb remains lit (left front).
The right side front and rear blinkers work great.
I have checked the fuses, replaced the bulb and cleaned the socket of the front left blinker and still have no results. While my next guess would be that the flasher unit is the problem, I don't believe the rear, or front right blinkers would blink if that was the problem.
Ran scanner and it showed codes C1215, C1226 and C1233. We checked the passenger front and found the wire to the sensor hanging off. It was damp inside so we dried it as much as we could. We reconnected the wire and tested. The light still on. We ran the scanner again, Only one code came up C1233. The book says ( Right front wheel speed circuit open or shorted)
C1233 - Right Front Wheel Speed Circuit Open or Shorted

My car has been missing after a recent spark plug change, so i did a smoke test and i see smoke coming from under the air cleaner and i see that the accessory vacuum line goes under there, could this be the cause of the misfire? i already checked all the sparkplug work and wires. and if this could be the problem how would i get to it 1998 Buick century 3.1.

Have 2005 Buick Century. There is a brake fluid leak somewhere between the brake fluid reservoir and the bottom of the car. Seeking a leak-stopping fluid such as the fluid used to stop a leak in a radiator.
View 18 RepliesI have a 1996 Buick Century that I started having problems with tonight.
As I was driving, I pressed the brake pedal down and it felt like I lost most if not all of the pressure in the brake system and it was a bit difficult to come to a complete stop for the rest of the trip.
I admit that the system hasn't been maintained in quite some time, but I recently filled up the brake fluid reservoir (2-3 weeks ago) after the brake dashboard light came on and the brakes worked just fine after this.
What is wrong with my car, and how do I fix it as cheaply as possible (or is it a cheap fix?)?
My car is a 1992 Buick Century with a 3.3 liter V6. My tail lights, parking lights and dashboard lights are out. I checked the fuse in the fuse panel and it's good. The light switch is good, I confirmed it by inserting a voltmeter in the empty fuse socket and turning the switch on and off. The wiring diagrams in my manual are not useful. The diagrams don't include the lighting circuits. Is there another hidden fuse someplace? Could it be a bad relay? If so, where the lamp relays are located?
View 4 RepliesUsually, the interior lights ( e.g. over rear doors ) will turn off after a while...but now they stay on as well as the two lights on the rear view mirror.
View 1 RepliesA couple of weeks ago my 2005 Buick century start making a noise when i hit the brakes and all the lights on the dash lit up like a christmas tree. The noise it makes when i hit the brakes is like humming sound and the pedal will get kinda spungy and push in and out, if i keep driving it stops and all the lights come on (abs, trac off, service engine, and sometimes the brake light as if the parking brake is on) after all these lights come on the noises stop and the brake pedal works fine. I was told that the anti lock brake pump was going bad but I didn't realize there was a pump.
View 3 RepliesMy 2000 Buick Century has an issue that whenever it rains really hard, after driving a while the ABS, Trac Off, and Service Vehicle Soon lights come on. I am assuming that part of the electrical connections are getting wet and causing the lights to come on. When there is no rain, obviously the lights don't come on. It's only done it one other time and it did it today. I was just curious what to do to fix it, before I jump into looking at all electrical connections which we all know can be hard to diagnose. By the way, the car has 64,000 miles on it if that makes any difference.
View 2 RepliesMy backup lights only work when I have one bulb or the other installed but not both. The other 4 mini lights in the same circuit on the trunk work. The backup lights do not work at all when the headlights are on. Could it be the backup light relay and where is that located? I checked wiring on the trunk and multiple bulbs.
View 5 RepliesI own a 1998 Chevy K1500 Silverado. About a year and a half ago my interior lights stopped turning off. I found that the only way to make the lights go out is to pull the interior light fuse. With the fuse pulled my lights will go out when the key is in the off position. With the key in any position besides off and the radio on my cab lights are on half bright. If I turn off the radio or pull the radio fuse the lights go out. My mechanic and I both investigated this and came up with the same answer: the Keyless Entry Module. After living with no cab lights for a year and a half (in northern New Hampshire) I broke down and paid the 180 bucks for the "Remote Function Actuation Module" (I had to take my dash apart and get the part number off the old module to figure out which one of three or four possible modules was used in my truck). Now that I have replaced the module I still have the same problem. If it's not the module then what is causing my lights to stay on all the time with the fuse in or come on half bright with the fuse pulled?
View 1 RepliesI have a 2000 Buick Century that I cannot get to start. While my wife was driving home it started to sputter (like running out of gas) and did a little back firing. She made it home and I put in some gas (Just to make sure) and the care cranks over but will not start. I have replaced the fuel filter, checked the spark plugs and replaced the CAM Sensor. The car still will not start.
View 5 RepliesMy wife has a 2000 Buick Century with about 150,000 miles on it. It has been relatively trouble free. Recently, the "low coolant" light began to come on.She took the car into a garage where she was told there was oil in the coolant and the sensor had been compromised. The cooling system was flushed and cleaned and a new sensor installed. The "low coolant" light continued to come on. She took the car back in. She was told the wrong sensor had been installed. When she went back for the car the second time, she was told the oil in the coolant was preventing the new sensor from working and there was nothing more the garage could do. I went in and asked questions, primarily how serious was the condition, and couldn't get a straight answer.
We are due to drive to Florida in November. My wife would like to take it to a garage there. Is it save to drive it as is? What are the implications of oil mixing with coolant? What is causing it to happen?
So my brake lights aren't working on my 1997 Buick Park Avenue, not even my middle one. All my bulbs, fuses, relays are good. My tail lights and hazards work fine. The circuit has continuity when the pedal is pressed and power going into the brake switch when the pedal is not pressed, but when pressed it has no power going in or out it just cuts off. I figured it was probably a ground then but I checked and all of the grounds are good.
View 5 RepliesMy 03 Buick century is overheating. I changed the thermostat and the water pump. And still overheats as soon As I start driving. I am also getting when it is overheating some misfiring in cylindar 1. I am going to reflush and bleed the coolant even though it seems to be full . i dont think it is disappearing. Is it Possible i have a blown headgasket or intake manifold leak?
View 4 RepliesI am having a very tricky problem with my Buick.
For approximately the last 4 months, it has been (at least according to the heat gauge on the dash) running pretty hot. Not overheating, but getting close. And it doesn't take long for it to get there. This all seems to have begun right around the time that my father and I flushed the coolant system.
Since then, I have replaced some parts, and learned a few things in the process.
I learned that there are bleeder screws which can be opened to let air bubbles out. And I have heard that the 3.1L is especially susceptible to them.
New parts which I have installed:
- thermostat
- coolant temperature sensor
- radiator cap
- upper radiator hose
- lower radiator hose
I have checked the water pump and it seems to be perfectly fine. No leaks. No signs of bad bearings. And it circulates coolant just fine. I have not been witness to either cooling fan, primary or auxiliary, switching on in a while.
The exact symptoms are these:
The heat gauge does not take long to get to mid-way point, but will sit at that point for a bit if the vehicle remains stationary. Once the vehicle is in significant motion, the heat gauge will climb fairly quickly, especially with moderately high RPMs. It WON'T touch the red though, but will get very very close to it. The car runs fine. It does seem to be a bit underpowered, but I am comparing it to my fiance's 1996 Olds Cutlass Ciera, which I believe has a different transmission. My Buick does not seem to have lost power since this problem arose. The cooling fans no longer kick on. The oil appears fine. The coolant as well. With the radiator cap off, coolant does not bubble out or shoot out.
I made sure after changing upper and lower hoses to fill the radiator, let the car run long enough for the thermostat to open, and then slowly poured more coolant into the radiator until it was full again. And the reservoir is at proper level and the the reservoir hose s not clogged.
I am not SURE, but I don't believe the radiator is clogged. I believe that covers it, at least as well as I can.
BTW, I do not know where the fan relays are, otherwise I would test the fans to see if they still work.
What the heck is up with my Buick? Also, it has 97,xxx miles on it, and the transmission fluid is at proper level and looks normal.
2002 Buick century will sometimes not start. Seems to correlate with warmer weather and happens after long drives. I try to restart within 10 minutes of turning off and it will start and then in a few seconds the car shakes and the engine dies. I can restart multiple times, but it will always die in a couple of seconds. If I wait an hour and retry, no problem. Once someone banged on the gas tank and that solved it. Mechanic cannot diagnose problem unless it dies while he is there. Should I replace the fuel pump or could it be something else?
View 4 RepliesMy grandpa's old wood paneled station wagon is sick. The idle seems to be getting rougher and rougher with every time I kill the battery (I've somehow left my headlights on four times in the past two months and needed a jump). It's to a point now where if I don't throw it in neutral at stop lights and keep a tiny bit of gas on the engine it stalls out.
Notes:*When it first gets jumped after being dead, if I stop even for a second, it dies instantly.*While cruising - it is fine. *It idles smoother stopped in neutral than it does stopped and in drive. *It seems a bit rougher with the engine is cold, but still rough and can stall with the engine hot. *Some random times it idles just fine (like for example the first few seconds on start up, and then it sounds like the engine is decreasing in rpm automatically, and then it is rough again).
Could the dying battery and rough idle be related?? The battery guy says "if it starts fine, the battery is fine" (it does start fine, although keeping the radio on for 20 minutes without it running will kill it).
Also other problems with my car in case this has anything to do with it: *I have a leaky tail pipe*my ABS has recently been randomly engaging at low speeds (next problem to work on...)
