Anti-lock brake lights came on, so put new anti-lock brakes on the car. After that the anti- lock light was still on and so was the service vehicle soon light. Can't figure it out.
i recently had this problem too, except i had all the lights on (ABS, service vehicle, trac-off, AND service engine) they are all easy to fix without spending more than 20-30$ for labour (depending how much your mechanic charges you) mine did it for free and he found out why the engine light is on afterwards too. so to fix all these lights (abs, trac-off, and service vehicle you MUST get another ABS cable (i went to a garage, they were towing a GM vehicle to the junk yard so i grabbed some scissors and cut BOTH abs cables on each side (good thing i did because one was bad) and braught them to my mechanic. the reason the lights come on is probably a defect or in my case my mechanic said it was salt buildup in the wires (on the drivers side) so he cut the wire off and rewired the new one and BOOM all the lights came off (service vehicle, abs, and trac-off) now for my service engine it says catalytic converter but im trying to put some fuel system cleaner to help it out i read somewhere that this is a defect of the car, so if you dont have that light yet, SELL your car ASAP for as much as you can get for it (after fixing the lights of course) and always google (car name+recalls) in the search bar to see what youre getting into, take care

Security light just started staying on all the time. Solution?
The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. Remember too, the TDM controls the security light. Sometimes you can have ALL the symptoms and no lights.

Where is the cigarette lighter fuse for a 2002 buick century
The fuse is located in the instrument panel fuse box. I have a picture of its location below. You have to open the passenger door to be able to see the cover. Below is also a diagram of the fuse layout and the fuse you want is the one marked "CIGAR LTR". It's in the 6th row up and the 6th one over from the left. This should be in your owners manual if you have one. If you don't and would like a copy, email me at [email protected] with your make, model and year. I will be happy to email you a copy & don't worry there is no cost for it. I hope this helps and good luck.

Alright. I have a 2002 Buick Century Custom with the 3.1 Liter (3100) V6 engine with 128,000 miles. Recently I have experienced a HUGE loss in Acceleration and I've noticed the engine sounds louder as if it's under hard pressure, the more the accelerator is pushed, regardless if I'm climbing a hill or on flat land. No, "Service Engine Soon" light or anything btw. So I took it to my friend who is a Free lance Auto-Mechanic. After letting him drive it a mile or so, his opinion was that the MAF (Mass Air Flow) sensor was failing. After the short drive, we parked in front of his shop, where he put the vehicle in park and revved it a few times. The "Service Engine Soon" light came on. He ran the codes and it came up as the MAF Sensor. So, the next day, he came by with a used MAF Sensor he picked up from a Junkyard that was compatible with my car. We installed it, and took it out on the road, STILL HAS THE SAME PROBLEM. So he tried unplugging all of the wires to the majority of the Sensors. No lights lit up on the dash. Fretful and worried that the ECM might be dying out, we disconnected the battery and opened up the Air Cleaner Assembly which is where the intake is, and also where the ECM is. After looking it over in fear of water ruining it, it looked fine, and had no visible defects. So here's my problem. Was the junkyard MAF Sensor also a dud, or does this sound like it's more of a computer issue? I'm really hesitant on buying a brand new MAF Sensor if thats not the problem. But, I also know that I'm looking at that or $300 for a new ECM and to get it programmed by the dealer. I'm very unsure about this, and so is my mechanic. We'd very much like some ideas opinions, or if you've had the same situation, what did you do to resolve this?
yes,it could be a bad sensor.
You didn't say if you did a tap test on while the engine was idling,take a small hammer and tap on the sensor with the handle,don't be afraid to tap it medium.if it stalls out the engine,get another one.
Second thing to check is when engine is at operatring temp and in park running,remove the oil fill cap,notice if the engine picks up speed,this would be the intake gasket has slipped out and is common in 3.1 engines.
Third,Does the car get slower with more acceleration,
if it does check for whistle sound at tailpipe,possible converter plugging up

climate control selection knob is broken The knob would not turn and when I pulled it off a piece of plastic droped out and now the knob turns freely but won't change the settings from AC to defrost or any other setting. I just turns freely
If I understand correctly, the same thing happened to me. It might just be the knob, if you can use pliers to rotate the metal piece where the knob connects then either buy a new knob or you could hot glue the old one in place. Just make sure you have it pointing in the right direction if you do.

location of sensor for troubleshooting po442 to cause check engine light to come on
P0442 OBD-II Trouble Code - Evaporative Emission Control System Leak Detected (small leak)
What does that mean?
This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
Symptoms
You likely won't notice any drivability problems.
Causes
A code P0442 most likely means one or more of the following has happened:
* A loose or improperly affixed gas cap
* A non-conforming gas cap (i.e. not factory/original brand)
* A small leak/hole in a fuel vapor hose/tube
* Other small leak in EVAP system
* Faulty vent o-ring seal
Possible Solutions
With a P0442, the most common repair is to:
* Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
* Otherwise, replace the gas cap, or
* Inspect the EVAP system for cuts/holes in tubes/hoses
