20 Most Recent 2001 Buick Century Questions & Answers

this happened to us on vacation. Catalytic coverter was plugged. It did this for a long time before overheating on a road trip. Have someone reputable check it, if it is hesitating a lot.

This is the bolt, but the answer is the size of the socket that fits it. If you don't have a full set of sockets and wrenches, doing job is impossible. If it is oversize, and I don't think it is, you can get larger specialized tool from Autozone for free and just a small returnable deposit. https://www.google.com/search?q=2001+Buick+Century+Custom+harmonic+balancer+bolt ..

NO. Thats a common thing, you need a Istrument cluster. I'm sure your local garage has a source to get one from.

P0xxx codes apply to all vehicles using the OBD2 system, P1xxx codes are manufacturer specific. Your codes mean... P0753 = Shift Solenoid "A" Electrical. P0502 = Vehicle Speed Sensor "A" Circuit Low. This is possibly 2 separate issues as one is a transmission fault code and the other is a vehicle speed sensor issue. Get the speed sensor repaired first as sometimes the bad signal from the sensor can confuse the transmission electronics causing the transmission to behave strangely.

I had this problem too, took it back the the shop and they tried to make it overheat, every time the fan would kick on at the 1st line over half. It's just the way this car is.

Check the switch

I had this same problem and I removed the long plastic dash piece that goes from door to door (after removing other pieces which hold that one in place) and then tilt the steering wheel to the lowest position. turn the key and put the car in gear 1 then shut the car off -this enables you to remove the instrument cluster, which is held in by 4 screws. Unclip the back of the instrument cluster and remove the circuit board. On the board to the right of the speedometer are 4 resistors which look like tiny black cylinders -these need to be replaced (if they haven't already fallen off the circuit board). I was missing two and I just touched the other two with my finger and they fell off. I soldered onto the board 150 ohm, 1/8 watt resistors ($1.99 for a packof 5 at Radio Shack). This entire process took me about 30 minutes. I put everything back together in the reverse order I took it apart and my instrument cluster, odometer and gear-shift indicator works fine.

The Variable Speed Sensor (VSS) has failed. You will have to get it replaced. Its all driven by an electrical signal sent to the cars computer by the VSS, and converted to SPEED, and DISTANCE driven.

I know this is an old post but my local library has auto repair manuals available for free online. Might help!

They are only supposed to come on IF the A/C is running. If you are not getting power to the correct area of the relay, it may be the ignition switch is worn out,

The relays should be in the fuse relay box in the engine compartment.The codes mean the computer tries to activate the fans and nothing happens. Could be the relays or a wiring problem.

you have to replace the entire instrument cluster. there is no way of just fixing the led readout for the gear select/odometer

Question edited for clarity. Question moved to sub category. The windows have a breaker, but it may be the switch or a break in the cabe between the door and the body. https://fuse-box.info/buick/buick-century-1997-2005-fuses-and-relays https://www.google.com/search?q=2001+Buick+Century.+power+window+relay+location ..

where is the location of the headlamp relay on a 2001 Buick century

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.
3.8L engine yhr test port is located at the pressure regulator under the trim cover.

There's this website www.reliable-store.com They have books on ALL vehicles. it covers wiring diagrams, electrical diagrams, fuse diagram, torque specs, PCV, error codes, fault codes, service info, repair info, parts info, owner's/service/repair/parts/maintenance manuals etc everything totally.. I have 1987 toyota 4runner model and I keep servicing and when needed repair it on my own. worth it !!!

Wow man that sounds to me like a temperature sensor that could be going out you might want to check the last job that you did to ensure that everything is put together the way it's supposed to be by the factory sometimes people do mechanic work and as you're going in to fix something something else breaks that they don't pay attention to you must pay full attention and everything in your engine bay

have they checked the PCM/ECM fuses? some might be bad or the computer itself. does the car run poorly, bad fuel economy? you could go the the emission check place to have it checked. for alot less money it will tell you if it is computer related before spending more for a mechanic to analyse it .$15 in WA State.

Take some picture on your phone and show them along with the vin number they should be able to tell from that.

My Buick had an ABS problem and since I had new brakes installed my mechanic disconnected the wiring. You still have full brakes and they will work fine but the ABS part won't work. Since i did not want to spend a lot of money I drove it that way for about three years. ABS is just an addition to help but not all cars have it.
